Heating ,Mechanical Shocks ,Cutting Tool Life ,Thermal Shocks - Abstract
This paper deals with the problem of thermal and mechanical shocks, which rising during operation, mostly at interrupted cut. Here will be solved their impact on the cutting edge tool life, the impact of coating technology on resistance to shocks and experimental determination of tool life in heating flame. Resistance of removable cutting edges against thermal and mechanical shock is an important indicator of quality as well as its abrasion resistance. Breach of the edge or its crumble may occur due to cyclic loading. We can observe it not only during the interrupted cutting (milling, turning areas abandoned hole or slot), but also in continuous cutting. This is due to the volatility of cutting force on cutting. Frequency of the volatility in this case depends on the type of rising chips (chip size element). For difficult-to-machine materials such as austenitic steel particularly happened at higher cutting speeds for the localization of plastic deformation in the shear plane and for the inception of separate elements substantially continuous chips. This leads to variations of cutting forces substantially greater than for other types of steel., {"references":["J. Houdek, K.

LYMPHANGIOMYOMATOSIS ,NEPHRECTOMY ,ETIOLOGY of diseases - Abstract
Tuberous sclerosis complex (TSC) or Bourneville disease is a rare autosomal dominant neurocutaneous disorder that affects various organs. Pulmonary involvement in TSC may consist of lymphangioleiomyomatosis (LAM) and multifocal micronodular pneumocyte hyperplasia (MMPH), occurring together or alone. In patients with TSC-LAM, chylous pleural effusion (CPE) is a rare, though well-recognized, complication with an unpredictable clinical course. In refractory or persistent CPE, optimal management remains a clinical challenge. We report the unique case of a 29-year-old Caucasian female, never-smoker, with definite TSC since infancy, characterized by seizures, facial angiofibromas ("adenoma sebaceum"), bilateral renal angiomyolipomas, hepatic angiomyolipomas, subcortical/cortical tubers, and subependymal nodules. At 27 years old, due to bleeding from the renal angiomyolipomas, she underwent nephrectomy, first of the right, and then a year and 9 months later, of the left kidney. She was hemodialysis dependent for the next five years until cadaveric kidney transplantation. The medical history was also remarkable for recurrent exudative lymphocytic PE despite repeated therapeutic thoracenteses, with first presentation at 23.5 years of age. Chylothorax was initially diagnosed at 24 years and 8 months old (PE triglycerides 4.53 mmol/L), and reconfirmed at age 29 (PE triglycerides 12.46-15.30 mmol/L). Computerized tomography scan of the thorax showed a large encapsulated PE in the left lung field, multiple thin-walled cysts (≤5 mm in diameter) in the lung parenchyma bilaterally, and mediastinal lymphadenopathy - all prominent features of LAM - as well as nodular pulmonary lesions (≤3 mm in diameter) consistent with MMPH. Given the persistent nature of the CPE, a five-day course of recombinant human factor XIII (FXIII) was administered intravenously. The chylothorax completely resolved within three months. There has been no recurrence of CPE on follow-up chest X-rays (i.e., total follow-up period of 53 months). This report suggests that the transglutaminase FXIII, a blood coagulation factor, may have an important clinical benefit in treating recurrent or thoracentesis-refractory CPE in TSC-LAM. To our knowledge, this is the first known case in the literature describing the successful treatment of CPE with FXIII in TSC-LAM. Because CPE is rare and there is currently no gold standard for its management, regardless of etiology, further research is warranted to investigate the potential clinical use of FXIII as an effective and safe treatment strategy in selected patients.

In the paper, investigations on the dynamic properties of air gauges are presented. The measurement of the amplitudes of back-pressure pk, dependent on the input signal angular frequency ω for the group of air gauges with various parameters has been performed. To evaluate the influence of the measuring chamber volume on the dynamical properties, a set of the model chambers with different dimensions has been prepared. The obtained results underwent a repeatability test in order to evaluate the uncertainty of time constant determination. Additionally, the impact of the feeding pipe was examined. Examinations of the time constant of typical backpressure air gauge led to the conclusion that it depends also on the actual pressure and that it may differ between the beginning and the end of the measuring range.

- Abstract
Importance: The incidence of early-onset colorectal cancer (younger than 50 years) is rising globally, the reasons for which are unclear. It appears to represent a unique disease process with different clinical, pathological, and molecular characteristics compared with late-onset colorectal cancer. Data on oncological outcomes are limited, and sensitivity to conventional neoadjuvant and adjuvant therapy regimens appear to be unknown. The purpose of this review is to summarize the available literature on early-onset colorectal cancer., Observations: Within the next decade, it is estimated that 1 in 10 colon cancers and 1 in 4 rectal cancers will be diagnosed in adults younger than 50 years. Potential risk factors include a Westernized diet, obesity, antibiotic usage, and alterations in the gut microbiome. Although genetic predisposition plays a role, most cases are sporadic. The full spectrum of germline and somatic sequence variations implicated remains unknown. Younger patients typically present with descending colonic or rectal cancer, advanced disease stage, and unfavorable histopathological features. Despite being more likely to receive neoadjuvant and adjuvant therapy, patients with early-onset disease demonstrate comparable oncological outcomes with their older counterparts., Conclusions and Relevance: The clinicopathological features, underlying molecular profiles, and drivers of early-onset colorectal cancer differ from those of late-onset disease. Standardized, age-specific preventive, screening, diagnostic, and therapeutic strategies are required to optimize outcomes.

Primary aorto-appendicular fistulas are extremely rare in clinical practice, and there are only 3 such cases reported in the available literature. The aim of this study is to present the case of a 68-year-old female patient with primary aorto-appendicular fistula accompanied by infected penetrating aortic ulcer (PAU). At the time of her hospital admission, the patient did not demonstrate any typical symptoms. Multidetector computed tomography imaging of aorta was performed during an additional preoperative examination and the PAU of the infrarenal aortic segment was detected. Other pathological changes were not found. The intraoperative findings confirmed the presence of the PAU firmly attached to the appendix and surrounding signs of inflammation. Appendectomy and partial resection of the PAU were performed, along with aortic reconstruction, using a Dacron tube graft and right renal artery reattachment. During the postoperative period, there were no complications, and the patient was discharged on the 10th postoperative day. Control medical examination and color duplex ultrasonography were performed 18 months after the surgery and they provided satisfactory results., (Copyright © 2019 Elsevier Inc. All rights reserved.)

- Abstract
Adie's syndrome (AS) and paraneoplastic sensorimotor neuropathy with cerebellar ataxia (PSN CA) are extremely rare, rapidly progressive, autoimmune diseases associated with the development of antibodies against neuronal-specific Hu proteins that are abnormally expressed in small-cell lung cancer (SCLC). We herein present the unique case of a 55-year-old obese woman, previous heavy smoker, who, during treatment with standard cisplatin-etoposide chemotherapy for limited-stage SCLC, developed simultaneous AS and worsening symptoms consistent with PSN CA that led to significant neurological disability and severe axonal electrophysiological pattern on nerve conduction studies. Serology confirmed the presence of low-titre type 1 antineuronal nuclear antibodies (ANNA-1), previously referred to as anti-Hu antibodies. Following plasmapheresis, immunosuppressive therapy and physical rehabilitation, the neurological symptoms progressively improved. The tumour completely regressed, with no recurrence detected on subsequent radiological examinations. The aim of this case was to highlight the importance of a multidisciplinary team approach for early recognition and rapid treatment of paraneoplastic neurological syndromes (PNS) as key to achieving significant recovery and marked improvement of the neurological deficit. This report extends the literature by confirming earlier studies showing that the presence of serum ANNA-1 in SCLC, an aggressive type of pulmonary carcinoma that is challenging to treat, may portend a more favourable prognosis and response to chemotherapy. Thus, patients with SCLC and new-onset neurological symptoms should be tested for ANNA-1. The role of a multimodality approach to treating PNS is also emphasized.

- Abstract
What is known and objectives: Multiple adverse drug reactions (ADRs) are expected, and thus should be prevented in the elderly comorbid patient on polypharmacy. Rosuvastatin is commonly prescribed for the treatment and prevention of atherosclerotic diseases, and in rare cases, is associated with rhabdomyolysis. Maprotiline is a tetracyclic antidepressant, infrequently used in the United States, but seemingly more broadly in European countries. Acute colonic pseudo-obstruction (Ogilvie's syndrome) caused by maprotiline has thus far, to our knowledge, not yet been described in the literature., Case Summary: We present a unique case of synchronous rhabdomyolysis and Ogilvie's syndrome in an 80-year-old lung cancer survivor following a recent ischemic stroke for which she was prescribed clopidogrel and rosuvastatin for secondary prevention, and maprotiline for post-stroke, new-onset insomnia and anxiety. The ADRs resolved on removal of the offending agents and initiation of conservative treatment. Retrospective pharmacogenetic testing of the patient's drug-metabolizing enzymes and transporters was performed to guide further management and prevent future potential drug interactions and ADRs. What is novel and conclusions: This is an interesting, albeit unfortunate, complex case that depicts the risk of rare adverse effects to medications and their potential relationship to pharmacogenetics. The impact of anticholinergic side effects of antidepressants on gastrointestinal motility, risk of myopathies with statins, increased susceptibility to ADRs caused by drug-drug interactions, and the utility of pharmacogenomic testing are discussed. The question whether commercially available pharmacogenomic tools are relevant for everyday use to direct patient care and reduce harmful drug-drug interactions is addressed and warrants further research. .

- Abstract
The ongoing search for effective antiplasmodial agents remains essential in the fight against malaria worldwide. Emerging parasitic drug resistance places an urgent need to explore chemotherapies with novel structures and mechanisms of action. Natural products have historically provided effective antimalarial drug scaffolds. In an effort to search nature's chemical potential for antiplasmodial agents, unconventionally sourced organisms coupled with innovative cultivation techniques were utilized. Approximately 60,000 niche microbes from various habitats (slow-growing terrestrial fungi, Antarctic microbes, and mangrove endophytes) were cultivated on a small-scale, extracted, and used in high-throughput screening to determine antimalarial activity. About 1% of crude extracts were considered active and 6% partially active (≥ 67% inhibition at 5 and 50 μg/mL, respectively). Active extracts (685) were cultivated on a large-scale, fractionated, and screened for both antimalarial activity and cytotoxicity. High interest fractions (397) with an IC50 < 1.11 μg/mL were identified and subjected to chromatographic separation for compound characterization and dereplication. Identifying active compounds with nanomolar antimalarial activity coupled with a selectivity index tenfold higher was accomplished with two of the 52 compounds isolated. This microscale, high-throughput screening project for antiplasmodial agents is discussed in the context of current natural product drug discovery efforts., (© 2014 Wiley Periodicals, Inc.)

- Abstract
Recent genomic studies have demonstrated that fungi can possess gene clusters encoding for the production of previously unobserved secondary metabolites. Activation of these attenuated or silenced genes to obtain either improved titers of known compounds or new ones altogether has been a subject of considerable interest. In our efforts to discover new chemotypes that are effective against infectious diseases, including malaria and methicillin-resistant Staphylococcus aureus (MRSA), we have isolated a strain of marine fungus, Leucostoma persoonii, that produces bioactive cytosporones. Epigenetic modifiers employed to activate secondary metabolite genes resulted in enhanced production of known cytosporones B (1, 360%), C (2, 580%) and E (3, 890%), as well as the production of the previously undescribed cytosporone R (4). Cytosporone E was the most bioactive, displaying an IC(90) of 13 µM toward Plasmodium falciparum, with A549 cytotoxicity IC(90) of 437 µM, representing a 90% inhibition therapeutic index (TI(90) = IC(90) A459/IC(90)P. falciparum) of 33. In addition, cytosporone E was active against MRSA with a minimal inhibitory concentration (MIC) of 72 µM and inhibition of MRSA biofilm at roughly half that value (minimum biofilm eradication counts, MBEC90, was found to be 39 µM).

- Abstract
Ponderal index (fetal weight in grams X 100 / (fetal length in centimeters)3) (PI) is one of the anthropometric methods used to diagnose impaired fetal growth. Irrespective of the infant's position on the growth-weight-for-gestational age charts, PI is low in malnourished infants and high in obese ones. As fetal growth is affected by ethnicity, geographic location and socioeconomic status, we developed standards for neonatal PI, and assessed the effects of gestational age, sex and maternal parity. Data on 5798 newborns from singleton pregnancies born in the Department of Gynecology and Obstetrics, Split University Hospital, were retrospectively analyzed. Over a 15-month period in 2000/2001, 5596 newborns from 24 to 42 weeks of gestation were born. The other 202 newborns, born from 24 to 34 weeks of gestation in the ten year period, 1990-1999, were added because of the small number of preterm infants; ensuring a minimum of 30 to fill up at least infants in each gestational week. All mothers were of Caucasian origin. Stillbirths and fetuses with congenital malformations were excluded. The 10th, 50th and 90th percentiles, mean values with standard deviation of PI and the 10th, 50th, and 90th percentiles of birth weight and birth length are presented separately at weekly intervals. PI showed linear correlation with gestational age from 24 to 39 weeks, after witch the data plateaued. Sex and parity had no impact on PI in infants born between 24 and 37 weeks. Analysis of variance revealed PI to be significantly higher in female than in male newborns, and in multiparous than in nulliparous infants after 37 weeks of gestation. In conclusion, gestational age is the most important factor of neonatal PI. The effects of sex and parity on PI should only be considered in term neonates.
