Cardiothoracic surgeries are life-saving procedures but often it results in various complications. Intraoperative cerebral oximetry monitoring used to detect regional cerebral oxygen saturation (rScO2) is a non-invasive method that provides prognostic importance in cardiac surgery. The main aim of the present study was to evaluate the association of intraoperative cerebral oxygen monitoring during cardiac surgery on postoperative complications. This was a case-controlled retrospective study conducted on adult patients, who underwent open-heart surgery in National Heart Institute, Malaysia. The case group comprised patients on protocolized cerebral oximetry monitoring. They were treated using a standardized algorithm to maintain rScO2 not lower than 20% of baseline rScO2. The control group comprised patients with matched demographic background, preoperative risk factors, and type of surgical procedures. Propensity score stratification was utilized to contend with selection bias. Retrospective analysis was performed on 240 patients (case group) while comparing it to 407 patients (control group). The non-availability of cerebral oximetry monitoring during surgery was the prominent predictor for all outcome of complications; stroke (OR: 7.66), renal failure needing dialysis (OR: 5.12) and mortality (OR: 20.51). Postoperative complications revealed that there were significant differences for risk of mortality (p

Germ cells are vulnerable to stress. Therefore, how organisms protect their future progeny from damage in a fluctuating environment is a fundamental question in biology. We show that in Caenorhabditis elegans, serotonin released by maternal neurons during stress ensures the viability and stress resilience of future offspring. Serotonin acts through a signal transduction pathway conserved between C. elegans and mammalian cells to enable the transcription factor HSF1 to alter chromatin in soon-to-be fertilized germ cells by recruiting the histone chaperone FACT, displacing histones, and initiating protective gene expression. Without serotonin release by maternal neurons, FACT is not recruited by HSF1 in germ cells, transcription occurs but is delayed, and progeny of stressed C. elegans mothers fail to complete development. These studies uncover a novel mechanism by which stress sensing by neurons is coupled to transcription response times of germ cells to protect future offspring.

Peripheral muscle dysfunction in Overweight (OW) and Obesity (OB) leads to fatigue and activity limitations. However, there are contradictory views regarding the exact level with regard to hand grip and quadriceps muscle strength in OW and OB. The main objective of the present systematic review was to synthesize the literature for the strength part of the hand grip and quadriceps muscle strength among OW and OB. Literature search of Scopus, EBSCO and PubMed databases from 01.01.2004 to 30.06.2016, was performed. We set our search strategy using the terms “overweight OR obesity” AND “muscle strength” AND “grip OR quadriceps”. Two reviewers administered established eligible criteria and extracted the data. Strengthening the Reporting of Observational studies in Epidemiology (STROBE) was used to assess the risk of bias. Sixteen articles which were included identified Handgrip Strength (HGS), shoulder flexor, elbow flexor and knee extensor were found to be altered. There were consistent results with an increase in quadriceps muscle strength, whereas differed results were found in hand grip to increase and decrease in muscle strength in the presence of OW and OB. It is concluded that HGS appeared to be diversified with findings of increased and decrease strength, whereas regarding the quadriceps muscles, the findings were homogeneous.

There is an increase in the incidence of cardiovascular diseases with aging and it is one of the leading causes of death worldwide. The main cardiovascular pathologies include atherosclerosis, myocardial infarction, hypertension and stroke. Chronic inflammation is one of the significant contributors to the age-related vascular diseases. Therefore, it is important to understand the molecular mechanisms of the persistent inflammatory conditions occurring in the blood vessels as well as the signaling pathways involved. Herein, we performed an extant search of literature involving PubMed, ISI, WoS and Scopus databases for retrieving all relevant articles with the most recent findings illustrating the potential role of various inflammatory mediators along with their proposed activated pathways in the pathogenesis and progression of vascular aging. We also highlight the major pathways contributing to age-related vascular disorders. The outlined molecular mechanisms, pathways and mediators of vascular aging represent potential drug targets that can be utilized to inhibit and/or slow the pathogenesis and progression of vascular aging.

Morgagni Hernia is a rare form of diaphragmatic hernia. It is mainly asymptomatic and often identified incidentally during surgery. Tension-free synthetic mesh repair is the preferred treatment modality. However, the use of synthetic mesh concurrently during a clean-contaminated surgery such as sleeve gastrectomy remains controversial due to the remote possibility of mesh infection. A middle-aged female 2 with BMI of 47 Kg/m was admitted electively for laparoscopic sleeve gastrectomy with concurrent umbilical hernia repair. Intra-operatively, a left Morgagni Hernia containing omentum and a segment of transverse colon was noted. She underwent a laparoscopic sleeve gastrectomy and simultaneous laparoscopic tension-free composite mesh repair of both Morgagni and umbilical hernia. Outpatient review three months later revealed excess weight loss of almost 30% with no recurrence of either hernia. In conclusion, the advantages of concurrent hernia repair during bariatric surgery outweigh the risk of mesh infection and should be performed to prevent future risk of visceral herniation and strangulation. Laparoscopic mesh repair of a Morgagni Hernia and umbilical hernia in the setting of an electively planned sleeve gastrectomy is feasible, effective and safe in the hands of a trained laparoscopic surgeon.

Congenital pseudarthrosis of tibia is a rare condition and it is highly associated with neurofibromatosis. The goals of surgery are to restore the tibial alignment, achieve bone union and re-establish the length of the tibia. The treatment includes resection of the pseudarthrosis followed by fixation with external fixation devices to perform callus distraction, intramedullary nail or open reduction and plate fixation in combination with bone graft. We present a case of a 16-year-old male with underlying neurofibromatosis and congenital pseudarthrosis of right distal third of tibia. Patient was treated with excision of the pseudarthrosis followed by reduction and fixation using locking compression plate and bone graft. Radiograph showed union of the tibia at eight months postoperation. Patient had limb length discrepancy of 10 cm and was ambulating with a shoe raised. At two years follow-up, there was no refracture of the tibia. The patient was satisfied with his current functional status and had adapted well. Due to his good functional outcome, he declined to undergo limb lengthening surgery. We thereby concluded that locking compression plate may be considered as a suitable option for the treatment of congenital pseudarthrosis of tibia.

Background: It is a common practice to heat cooking oil and reuse it in order to cut expenses. The use of repeatedly heated cooking oil predisposes to various cardiovascular diseases. Virgin coconut oil (VCO) is reported to possess antioxidant action. Aim: The study aimed to determine the effect of heating of VCO on the blood pressure (BP) and inflammatory bio-markers. Methods: Thirty male Sprague-Dawley rats were divided into five groups and were fed with the following diet for 24 weeks: normal rat chow (control); chow + fresh VCO (FVCO); chow + VCO heated once (1HVCO); chow + VCO heated five times (5HVCO) and chow + VCO heated ten times (10HVCO). BP was measured at baseline and four weekly for 24 weeks. Blood was collected at baseline and at the end of study to measure plasma TXB2, PGI2, VCAM-1, ICAM-1 and LDH enzyme activity. Results: BP increased significantly in the 5HVCO and 10HVCO groups compared to the control and FVCO groups. The 5HVCO and 10HVCO diet caused a significant increase in the plasma TXB2 and a significant decrease in the plasma PGI2 level. The plasma levels of VCAM-1, ICAM-1 and CRP were significantly increased in the 10HVCO group. Conclusion: Repeatedly heated VCO caused an elevation in the BP. The BP elevation was associated with a significant increase in the inflammatory bio-markers (VCAM-1, ICAM-1 and CRP), TXB2 and a significant reduction in the plasma PGI2 level.

Langerhans cell histiocytosis (LCH), previously known as Histiocystosis X, is a rare idiopathic disease caused by a build-up of langerhan cells in the body. LCH has a heterogenous form of clinical presentation and presents with varying degree of severity. The severity often depends on the disease burden. LCH can manifest as a unifocal disease, multifocal-unisystem or multifocal-multisystem disease with the latter being more fatal than the rest. Risk organ involvement confers a grim prognosis. Perianal lesions are extremely rare skin manifestation of LCH with only few cases reported in the past. Vinca-alkaloids and steroid therapy have been shown to be effective in a large percentage of those presenting with LCH. This case report highlights the diagnosis and management of LCH presenting as a painful perianal ulcer in the background of newly diagnosed diabetes insipidus.

Mothers with infants in the Neonatal Intensive Care Unit (NICU) are at a higher risk of postpartum depression (PPD). Risk factors of PPD include environmental factors, psychological factors and biological factors. In this review, the aim was to identify the prevalence of PPD and its associated risk factors among mothers with infants in NICU. The relationship between dietary intake in relation to traditional postpartum practices with PPD is also discussed. Findings showed that PPD among mothers with infants in NICU was prevalent, ranging between 12.1% and 68%. Factors such as preterm birth, long hospitalisation and maternal role alteration were the most associated risk factors contributing to PPD. Consumption of food based on traditional practices was found to influence maternal mental health. Therefore, a rational approach in addressing mental health issues and adhering traditional food practices is needed in order to promote a postpartum mother's safe and healthy well-being.

Metabolic syndrome (MetS) has become a major clinical challenge worldwide due to rise of urbanisation, surplus energy intake, increasing obesity and sedentary lifestyle. C-reactive protein (CRP), interleukin-6 (IL-6) and interleukin-18 (IL-18) are associated with MetS. We performed a systematic review to investigate the effects of exercise on these markers in MetS patients and therefore to determine the best exercise regime for them. We searched Medline (Pubmed and Ovid), Scopus and CINAHL databases. The searches were standardized by using the same search strategy which included the terms such as ‘metabolic syndrome’, ‘CRP’, ‘IL-6’, ‘IL-18’ and ‘exercise’. Only clinical human studies published from Jan 2007 to May 2018 were included. A total of 11 clinical trials (466 participants) were selected. Majority of the studies were randomized controlled studies (90.9%). All studies showed a decrease in serum levels of the biomarkers. However, not all were statistically significant. The main type of exercise in most of the studies was aerobic. Aerobic-resistance exercise was more effective rather than aerobic alone, but aerobic exercise was the only effective as a sole intervention. Aerobic exercise showed promising role as the main lifestyle intervention in MetS. It is concluded that patients with MetS should have combined aerobic-resistance exercise.

While the average human life span continues to increase, there is little evidence that this is leading to a contemporaneous increase in “healthy years” experienced by our aging population. Consequently, many scientists focus their research on understanding the process of aging and trialing interventions that can promote healthspan. The 2021 Midwest Aging Consortium consensus statement is to develop and further the understanding of aging and age-related disease using the wealth of expertise across universities in the Midwestern United States. This report summarizes the cutting-edge research covered in a virtual symposium held by a consortium of researchers in the Midwestern United States, spanning topics such as senescence biomarkers, serotonin-induced DNA protection, immune system development, multisystem impacts of aging, neural decline following severe infection, the unique transcriptional impact of calorie restriction of different fat depots, the pivotal role of fasting in calorie restriction, the impact of peroxisome dysfunction, and the influence of early life trauma on health. The symposium speakers presented data from studies conducted in a variety of common laboratory animals as well as less-common species, including Caenorhabditis elegans, Drosophila, mice, rhesus macaques, elephants, and humans. The consensus of the symposium speakers is that this consortium highlights the strength of aging research in the Midwestern United States as well as the benefits of a collaborative and diverse approach to geroscience.

Ischemic stroke caused by occlusion of cerebral artery is responsible for the majority of stroke that increases the morbidity and mortality worldwide. Diabetes mellitus (DM) is a crucial risk factor for ischemic stroke. Prolonged DM causes various microvascular and macrovascular changes, and blood-brain barrier (BBB) permeability that facilitates inflammatory response following stroke. In the acute phase following stroke, BBB disruption has been considered the initial step that induces neurological deficit and functional disabilities. Stroke outcomes are significantly worse among DM. In this article, we review stroke with diabetes-induce BBB damage, as well as underlying mechanism and possible therapeutic targets for stroke with diabetes.

Postoperative Cognitive Dysfunction (POCD) refers to the condition of neurocognitive decline following surgery in a cognitive and sensory manner. There are several risk factors, which may be life-threatening for this condition. Neuropsychological assessment of this condition is very important. In the present review, we discuss the association of apolipoprotein epsilon 4 (APOE ε4) and few miRNAs with POCD, and highlight the clinical importance for prognosis, diagnosis and treatment of POCD. Microarray is a genome analysis that can be used to determine DNA abnormalities. This current technique is rapid, efficient and high-throughout. Microarray techniques are widely used to diagnose diseases, particularly in genetic disorder, chromosomal abnormalities, mutations, infectious diseases and disease-relevant biomarkers. MicroRNAs (miRNAs) are a class of non-coding RNAs that are widely found distributed in eukaryotes. Few miRNAs influence the nervous system development, and nerve damage repair. Microarray approach can be utilized to understand the miRNAs involved and their pathways in POCD development, unleashing their potential to be considered as a diagnostic marker for POCD. This paper summarizes and identifies the studies that use microarray based approaches for POCD analysis. Since the application of microarray in POCD is expanding, there is a need to review the current knowledge of this approach.

A 67-year-old man of Chinese descent presented with a painless nodular lesion that had been present on his right forearm for the previous 3 months. A single, well-defined, dome-shaped, firm nodule with a central keratin plug surrounded by erythema was noted. Keratoacanthoma with secondary bacterial infection was suspected and the patient underwent an excision biopsy. Biopsy of the nodule and immunohistochemical staining supported a diagnosis of nodular malignant melanoma. It should be noted both that nodular malignant melanoma may present with a wide variety of clinical appearances, and that the lack of melanin pigment in nodular malignant melanoma may hinder the diagnosis of this aggressive tumour.

We present a 20-year-old Malay male whom we believe has Proteus syndrome, a rare congenital disorder of asymmetrical overgrowth of body tissues. There are fewer than 100 confirmed cases reported worldwide thus the clinical presentation and histopathological findings are of significance. Our patient presented with an overgrown right small finger and subcutaneous purplish pigmentation over his left upper arm and chest since birth. His small finger gradually increased in size. He had no abnormalities in sensation or power. Radiographs revealed a delta shaped middle phalanx of the small finger. His activities of daily living were uninterrupted but he requested debulking surgery for cosmetic reasons. Histopathological examination reported hypertrophic fatty tissue composed of well formed lobules of mature adipocytes interspersed with fibrous elements.

Dural metastasis is a rare entity in clinical practice. We report a case of dural metastasis secondary to thyroid carcinoma, which on both preoperative CT and MRI and at surgery had the typical appearance of a meningioma. Histopathological findings confirmed metastatic follicular thyroid carcinoma as a primary site. Although rare, dural metastases can mimic a meningioma. Our experience in this case has led us to consider metastasis as a differential diagnosis even when a meningioma is suspected. We believe that reporting of the case of dural metastasis mimicking a meningioma may help clinicians in future.

Accessory phrenic nerve ,Incidence ,Variation ,Surgical significance ,Medicine - Abstract
The description of accessory phrenic nerve (APN) in the standard textbooks and available literature is vague and sometimes limited to few lines. The incidence of APN varies a great deal from 17.6 % to 80.9 % in the available literature. The aim of the present study was to calculate the incidence and variation of APN in Indian population. Material and methods: Forty five adult formalin-fixed cadavers (35 male, 10 female; 90 sides) used for gross anatomy dissection for undergraduates; during the 2 year period 2006–2007 were considered. Findings were recorded at different stages of the dissection. Results: Out of 90 body sides studied, the APN was present in 48 sides (53.3 %). In 17 of the above sides the APN was confined to the cervical region (Cervical type) and in 31 sides the APN entered the thorax (Thoracic type), all anterior to the subclavian vein (SV). In eleven specimens the APN was found bilaterally. Conclusion: The incidence of APN, with its course and relation to the various structures in cervical and thoracic region will help the surgeons while performing internal thoracic artery (ITA) grafting and other radical neck surgery.

scapula ,ligament ,anomalies ,ossification ,entrapment ,case report. ,Medicine - Abstract
The superior transverse scapular ligament (STSL) bridges the suprascapular notch, converting it into a suprascapular foramen. The suprascapular nerves and the vessels traverse through the suprascapular foramen of the scapula. Often the STSL is ossified to produce compression of the suprascapular nerves producing resultant symptoms. The entrapment of the suprascapular nerve by the ossified STSL may result in symptoms like pain in the shoulder region and also result in wasting and weakness of the supraspinatus and infraspinatus muscles. Such a condition has to be differentiated from other conditions like rotator cuff tears. Often asymptomatic cases make the diagnosis difficult. The present study reports the anomalous ossified STSL detected in a bone specimen, discusses its anatomical and radiological aspects and describes its clinical implications.

alzheimer’s disease, ageing population, caregivers ,Medicine - Abstract
The demographic profile of the Asian population is rapidly changing, with a fast increasing ageing population, owing to an increase in longevity and a decreasing birth rate. Moreover, due to improved medical facilities and the increased aged population, Alzheimer’s disease (AD) is fast emerging as a major health problem in many Asian countries. As curative treatment for AD is still elusive, care giving is an important component of the management of AD. While Western countries have recognised this issue, besides highly industrialized Japan, the Asian initiative has been relatively slow. This article aims to address issues involved in caregiving in AD in some Asian countries.

The incidence of urologic cancers, including kidney, upper tract urothelial, and bladder malignancies, is increasing globally, with a high percentage of cases showing metastasis upon diagnosis and low five-year survival rates. MicroRNA (miRNA), a small non-coding RNA, was found to regulate the expression of oncogenes and tumor suppressor genes in several tumors, including cancers of the urinary system. In the current review, we comprehensively discuss the recently reported up-or down-regulated miRNAs as well as their possible targets and regulated pathways involved in the development, progression, and metastasis of urinary tract cancers. These miRNAs represent potential therapeutic targets and diagnostic/prognostic biomarkers that may help in efficient and early diagnosis in addition to better treatment outcomes.

Introduction: Parkinson's disease (PD) is the second most common neurodegenerative disease caused by selective degeneration of dopaminergic neurons in the substantia nigra. Metallothionein has been shown to act as a neuroprotectant in various brain injury. Thus, this study aims to identify the effects of full length human metallothionein 2 peptide (hMT2) in paraquat-induced brain injury in the zebrafish.Methodology: A total of 80 adult zebrafish were divided into 4 groups namely control, paraquat-treated, pre-hMT2-treated, and post-hMT2-treated groups. Fish were treated with paraquat intraperitoneally every 3 days for 15 days. hMT2 were injected intracranially on day 0 (pre-treated group) and day 16 (post-treated group). Fish were sacrificed on day 22 and the brains were collected for qPCR, ELISA and immunohistochemistry analysis.Results: qPCR analysis showed that paraquat treatment down-regulated the expression of genes related to dopamine activity and biosynthesis (dat and th1) and neuroprotective agents (bdnf). Paraquat treatment also up-regulated the expression of the mt2, smtb and pro-inflammatory genes (il-1α, il-1β, tnf-α and cox-2). hMT2 treatment was able to reverse the effects of paraquat. Lipid peroxidation decreased in the paraquat and pre-hMT2-treated groups. However, lipid peroxidation increased in the post-hMT2-treated group. Paraquat treatment also led to reduction of dopaminergic neurons while their numbers showed an increase following hMT2 treatment.Conclusion: Paraquat has been identified as one of the pesticides that can cause the death of dopaminergic neurons and affect dopamine biosynthesis. Treatment with exogenous hMT2 could reverse the effects of paraquat in the zebrafish brain.

Introduction: Sedentary behaviour or physical inactivity has been relatively prevalent among young adults globally. Multiple studies pointed out that Malaysia has been listed as one of the Asian countries with high prevalence of inactivity. Objective: This study aimed to examine the heart rate variability (HRV) and muscle strength among young adults in order to identify the early impact of this behaviour on their physiological and physical health. Method: This cross-sectional study involved 185 healthy male adults aged 18-25 years old. Participants’ height and body compositions were measured and their level of physical activities were obtained using Short Questionnaire to Assess Health (SQuASH). Those with less than 150 minutes per week of physical activity engagement were classified as sedentary. Their HRV was analysed as a determinant for early physiological change that was influenced by the sedentary behaviour. Muscle strength of upper and lower body was assessed via handheld dynamometer to identify the physical fitness associated to the behaviour. Results: Among the participants that volunteered in this study, approximately 44% were classified as sedentary. Analyses revealed that those with sedentary behaviour had lower variability of their HRV and lower muscle strength as compared to those who engaged with at least 150 minutes per week of physical activities. Conclusion: The highlighted evidence of the difference on parameters of HRV and muscle strength with this behaviour suggested that these parameters were suitable parameters to be utilised in determining subclinical improvement on health with any intervention to curb sedentary behaviour.

Transient ischemic attack (TIA) of the fornix causes a spectrum of memory deficits, which increases the contributions of vascular disease to dementia which is known as early-onset dementia. As the fornix, the white matter bundle, serves as the major efferent pathway connecting the hippocampus with other human limbic structures, a variety of lesions that damage the fornix could lead to significant memory impairment. Therefore, the blood supply of fornix is a concern. This study aims to study the arterial supply of fornix. Thirty fresh human cadaveric heads were used. They were preserved by the mixture of fixation solution for fornix anatomical dissection and injected with coloured latex solution for visualization of cerebral vasculature through 6 critical steps of approaches. The result showed that the fimbriae of fornix were mainly supplied by the branches of posterior cerebral artery (PCA) and two cases were found to have the anastomoses of those branches with the choroidal artery (ChA). The proposed technique confirmed the ability of coloration of human cerebral vasculature by using colored latex solution which penetrated into cerebral small vessels leading to a precise understanding of the arterial supply of fornix in human brain which is essential for neurosurgeon, neurosurgical training and researchers.

The incidence of post-menopausal osteoporosis is increasing globally. In post-menopausal osteoporosis, there is deficiency in oestrogen level resulting in bone loss and fractures. Bone formation is under the control of different hormones. In the present review, we highlight few pathways such as RANKL/RANK, apoptosis and Wnt/β-catenin signalling pathways and phytoestrogens involved in the bone metabolism. RANKL/RANK signalling is responsible for regulating the formation and activation of multinucleated osteoclasts from their precursors which is responsible for the survival of normal bone remodelling. Apoptosis regulates the development, growth and maintains the bone tissues. The Wnt pathway is an important pharmacological target for bone anabolic drugs and its future discovery. In today’s world, herbal remedies are used to treat post-menopausal osteoporosis as these products contain phytoestrogens. These phytoestrogens are oestrogen like compounds which influence bone metabolism. The phytoestrogens provide better therapeutic effect in reducing the RANKL, osteoclastogenesis, inflammatory markers, and increase the osteogenic markers in the bone cells or osteoblasts. We discuss the mechanism of action of few phytoestrogens such as genistein, daidzein and equol which are beneficial for improvement of the bone health. Daidzein enhances osteoblast growth via the upregulation of BMP expression in primary osteoblast cells and it is a potential antiosteoporotic agent. Genistein also possesses antioestrogenic property by virtue of its competitive binding to the same receptors as oestradiol. Equol regulates the bone loss via hemopoiesis and inflammatory cytokine production. Thus, phytoestrogens could be efficiently used as osteoprotective agents for the treatment of individuals with post-menopausal osteoporosis.

Aorta is the largest artery in the human body. Its starting point is the aortic orifice of the aortic valve and it terminates at the level of the fourth lumbar vertebra. The main function of the aorta is to transport oxygenated blood to supply all the organs and cells. With advancing age, the structure and hence the function show progressive changes. Various changes in the aortic morphology include the luminal diameter of aorta, whole length of the aorta, thickness, the microstructural components also change, and these include collagen, elastin and smooth muscle cells. In addition, the dimensions of all segments of the aorta increase with age in both sexes. Since age is a major risk factor for degenerative change and diseases affecting the aorta, understanding the detailed anatomy of the aorta may provide essential information concerning the age-associated process of the aorta. Knowledge of the morphological changes in the aorta is also important for future clinical therapies pertaining to aortic disease. Additionally, the information regarding the structural changes with age may be applied for age determination. This review describes the overview of the anatomy of the aorta, age related changes in the morphology of the aorta and aortic diseases.

Discoid meniscus is the commonest anatomical aberration of the knee joint, among rare cases such as bilateral separated lateral meniscus, accessory lateral meniscus, partial deficiency of the lateral meniscus and double-layered lateral meniscus. An 11-year- old girl presented with history of chronic pain in her right knee for the last 6 months. The problem disturbed her involvement in the sport activities at school. Clinical examination revealed a clicking sensation on knee extension with lateral joint line tenderness. Magnetic resonance imaging (MRI) of her right knee showed torn posterior horn of lateral meniscus. Arthroscopy examination revealed a discoid meniscus with absence posterior horn. Posterior horn deficient discoid meniscus is a rare form of a congenital meniscus anomaly. We as clinicians believe that the abnormal shaped meniscus may pose a diagnostic challenge clinically and radiologically. Presentation of this case may be beneficial for orthopaedicians in their daily clinical practice.

Abstract: There is an increase in the incidence of inflammatory eye diseases worldwide. Several dysregulated inflammatory pathways, including the NOD-like receptor protein 3 (NLRP3) inflammasome, have been reported to contribute significantly to the pathogenesis and progression of ophthalmic diseases. Although the available allopathic/ conventional medicine has demonstrated effectiveness in managing eye diseases, there is an ongoing global demand for alternative therapeutics with minimal adverse drug reactions, easy availability, increase in patient compliance, and better disease outcomes. Therefore, several studies are investigating the utilization of natural products and herbal formulations in impeding inflammatory pathways, including the NLRP3 inflammasome, in order to prevent or manage eye diseases. In the present review, we highlight the recently reported inflammatory pathways with special emphasis on NLRP3 Inflammasomes involved in the development of eye diseases. Furthermore, we present a variety of natural products and phytochemicals that were reported to interfere with these pathways and their underlying mechanisms of action. These natural products represent potential therapeutic applications for the treatment of several inflammatory eye diseases.

Cardiothoracic surgeries are life-saving procedures but often it results in various complications. Intraoperative cerebral oximetry monitoring used to detect regional cerebral oxygen saturation (rScO2) is a non-invasive method that provides prognostic importance in cardiac surgery. The main aim of the present study was to evaluate the association of intraoperative cerebral oxygen monitoring during cardiac surgery on postoperative complications. This was a case-controlled retrospective study conducted on adult patients, who underwent open-heart surgery in National Heart Institute, Malaysia. The case group comprised patients on protocolized cerebral oximetry monitoring. They were treated using a standardized algorithm to maintain rScO2 not lower than 20% of baseline rScO2. The control group comprised patients with matched demographic background, preoperative risk factors, and type of surgical procedures. Propensity score stratification was utilized to contend with selection bias. Retrospective analysis was performed on 240 patients (case group) while comparing it to 407 patients (control group). The non-availability of cerebral oximetry monitoring during surgery was the prominent predictor for all outcome of complications; stroke (OR: 7.66), renal failure needing dialysis (OR: 5.12) and mortality (OR: 20.51). Postoperative complications revealed that there were significant differences for risk of mortality (p

Normally the ulnar artery and the ulnar nerve pass superficial to the flexor retinaculum of the wrist. In the present study, we describe an ulnar artery and ulnar nerve which passed deep to the flexor retinaculum and an absent superficial palmar arch. Abnormal course of ulnar nerve and ulnar artery passing deep to the flexor retinaculum with absence of a characteristic superficial palmar arch is a rare finding. The ulnar vessels and nerves when passing deep to the flexor retinaculum are vulnerable to compression and may be important for clinicians diagnosing compressive neuropathies and surgeons operating on the wrist.

The combination of rectus sternalis muscle, anomalous attachment of pectoralis minor muscle and supernumerary ribs in a single individual has not been reported by any research study, to the best of our knowledge. We report a left-sided rectus sternalis muscle, altered attachment pattern of the pectoralis minor muscle and the presence of a right-sided supernumerary rib in the third intercostal space of a 42-year-old male cadaver. Anatomical knowledge of rectus sternalis muscle may be important for radiologists who may misinterpret it to be a bulging mass in routine mammography and for surgeons performing reconstructive surgery. Variations of pectoralis minor muscle may influence the kinematics around the scapula and may be important for biomechanical studies. The shadow of the supernumerary rib may overlap and confuse radiologists interpreting roentgenograms. The aim of the study was to highlight the complex musculoskeletal defects and discuss their academic and clinical significance.

Medicine ,Science - Abstract
HYPK (Huntingtin Yeast Partner K) was originally identified by yeast two-hybrid assay as an interactor of Huntingtin, the protein mutated in Huntington's disease. HYPK was characterized earlier as an intrinsically unstructured protein having chaperone-like activity in vitro and in vivo. HYPK has the ability of reducing rate of aggregate formation and subsequent toxicity caused by mutant Huntingtin. Further investigation revealed that HYPK is involved in diverse cellular processes and required for normal functioning of cells. In this study we observed that hyperthermia increases HYPK expression in human and mouse cells in culture. Expression of exogenous Heat Shock Factor 1 (HSF1), upon heat treatment could induce HYPK expression, whereas HSF1 knockdown reduced endogenous as well as heat-induced HYPK expression. Putative HSF1-binding site present in the promoter of human HYPK gene was identified and validated by reporter assay. Chromatin immunoprecipitation revealed in vivo interaction of HSF1 and RNA polymerase II with HYPK promoter sequence. Additionally, acetylation of histone H4, a known epigenetic marker of inducible HSF1 binding, was observed in response to heat shock in HYPK gene promoter. Overexpression of HYPK inhibited cells from lethal heat-induced death whereas knockdown of HYPK made the cells susceptible to lethal heat shock-induced death. Apart from elevated temperature, HYPK was also upregulated by hypoxia and proteasome inhibition, two other forms of cellular stress. We concluded that chaperone-like protein HYPK is induced by cellular stress and under transcriptional regulation of HSF1.

Breast cancer estrogen receptor (ER) status is one of the strong additional factors in predicting response of patients towards hormonal treatment. The main aim of this study was to assess the morphological characteristics and proliferative activity using MIB-1(Ki-67) of estrogen receptor negative invasive breast ductal carcinoma (NOS type) as well as to correlate these features with clinicopathological data. We also aim to study the expression of c-erbB2 in ER negative breast tumors. High proliferative rate (MIB-1 above 20%) was observed in 63 (63.6%) of 99 ER negative tumors and that these tumors were associated with high expression of c-erbB2 (57.6%). We observed that MIB-1 is a reliable independent prognostic indicator for ER negative infiltrating ductal carcinoma in this study.

Technology ,Medicine ,Science - Abstract
This review is to examine the current literatures on the relationship between periodontitis and hypertension as well as to explore the possible biological pathways underlying the linkage between these health conditions. Hypertension is one of the major risk factors for cardiovascular diseases. Oxidative stress and endothelial dysfunction are among the critical components in the development of hypertension. Inflammation has received much attention recently and may contribute to a pivotal role in hypertension. Periodontitis, a chronic low-grade inflammation of gingival tissue, has been linked to endothelial dysfunction, with blood pressure elevation and increased mortality risk in hypertensive patients. Inflammatory biomarkers are increased in hypertensive patients with periodontitis. Over the years, various researches have been performed to evaluate the involvement of periodontitis in the initiation and progression of hypertension. Many cross-sectional studies documented an association between hypertension and periodontitis. However, more well-designed prospective population trials need to be carried out to ascertain the role of periodontitis in hypertension.

The mechanisms by which maternal stress alters offspring phenotypes remain poorly understood. Here we report that the heat shock transcription factor HSF-1, activated in theC. elegansmaternal germline upon stress, epigenetically programs the insulin-like receptordaf-2by increasing repressive H3K9me2 levels throughout thedaf-2gene. This increase occurs by the recruitment of theC. elegansSETDB1 homolog MET-2 by HSF-1. Increased H3K9me2 levels atdaf-2persist in offspring to downregulatedaf-2,activate theC. elegansFOXO ortholog DAF-16 and enhance offspring stress resilience. Thus, HSF-1 activity in the mother promotes the early life programming of the insulin/IGF-1 signaling (IIS) pathway and determines the strategy of stress resilience in progeny.One Sentence SummaryHSF-1 recruits MET-2 to silencedaf-2and mediate early life programming ofC. elegansupon stress

Medicine ,Science - Abstract
BACKGROUND: Exercise training programs have emerged as a useful therapeutic regimen for the management of type 2 diabetes mellitus (T2DM). Majority of the Western studies highlighted the effective role of exercise in T2DM. Therefore, the main aim was to focus on the extent, type of exercise and its clinical significance in T2DM in order to educate the clinicians from developing countries, especially in Asians. METHODS: Pubmed, Science Direct, Scopus, ISI Web of Knowledge and Google scholar were searched using the terms "type 2 diabetes mellitus," "type 2 DM," "exercise," and/or "physical activity," and "type 2 diabetes mellitus with exercise." Only clinical or human studies published in English language between 2000 and 2012 were included. Certain criteria were assigned to achieve appropriate results. RESULTS: Twenty five studies met the selected criteria. The majority of the studies were randomized controlled trial study design (65%). Most of the aerobic exercise based studies showed a beneficial effect in T2DM. Resistance exercise also proved to have positive effect on T2DM patients. Minimal studies related to other types of exercises such as yoga classes, joba riding and endurance-type exercise were found. On the other hand, United States of America (USA) showed strong interest of exercise management towards T2DM. CONCLUSION: Aerobic exercise is more common in clinical practice compared to resistance exercise in managing T2DM. Treatment of T2DM with exercise training showed promising role in USA. A large number of researches are mandatory in the developing countries for incorporating exercise in the effective management of T2DM.

Germ cells are vulnerable to stress. Therefore, how organisms protect their future progeny from damage in a fluctuating environment is a fundamental question in biology. We show that inCaenorhabditis elegans, serotonin released by maternal neurons during stress ensures the viability and stress tolerance of future offspring by enabling the transcription factor HSF1 to alter chromatin in soon-to-be fertilized germ cells by recruiting the histone chaperone FACT, displacing histones, and initiating protective gene expression. Without maternal serotonin signaling by neurons, FACT is not recruited by HSF1 in germ cells, transcription occurs but is delayed, and progeny of stressedC. elegansmothers fail to complete development. Serotonin acts through a signal transduction pathway conserved betweenC. elegansand mammalian cells to facilitate HSF1 to recruit FACT. These studies uncover a novel mechanism by which stress sensing by neurons is coupled to transcription response times of germ cells to protect future offspring.
