The spread of COVID-19 has resulted in reports of increase in stress, anxiety, and depression across society, especially in people who have tested positive for COVID-19, which affects their mental health and well-being. This article reports a quasi-randomized controlled study conducted in the COVID wards of a hospital to examine the efficacy of add-on yoga intervention in reducing stress, anxiety, and depression in COVID-affected patients under quarantine. The peripheral capillary oxygen saturation level and heart rate of the COVID-19-affected patients were also measured. A total of 62 COVID-19-positive patients participated in the study. The participants were randomized into a control group (n = 31), which received conventional medical treatment alone, and a yoga intervention group (n = 31), which received 50 minutes of yoga intervention along with the conventional medical treatment. Standardized Hospital Anxiety and Depression Scale, Generalized Anxiety Disorder–7 Item, Patient Health Questionnaire–9, and Perceived Stress Scale were administered at the beginning and end of the quarantine period. A significant decrease in stress, anxiety, and depression was observed in the patients who undertook the add-on yoga intervention. There was also a significant decrease in anxiety in the control group, but the intervention group had a larger decrease compared to the control group. Further significant improvements in oxygen saturation and heart rate levels were observed in the group of patients who were practicing yoga, but no significant improvement was observed in the control group. Findings of this study suggest that yoga intervention can be an effective add-on practice in reducing stress, anxiety, and depression levels of COVID-19 patients. [ABSTRACT FROM AUTHOR]

Polyvinylcarbazole (PVK) exhibits excellent interface properties despite its structural properties playing a dominant role in nanocomposites. In the present work, we attempted to identify the interface and the molecular mechanism in pure and nano ZnO doped PVK samples. The performance of solution-cast foil samples of pure and nano ZnO sensitized PVK samples with similar (Al-Al) electrode combinations was studied by varying temperature from 30 to 170 °C. Polymer samples exhibit dielectric loss maxima around 100±10 C. The peak is shifted towards lower temperatures, and variation is found in short circuit thermally stimulated discharge current (TSDC) study. The results show that the polymer interface and matrix behavior are suitable for microelectronic device applications. The location of the TSDC α-peak is found to be comparable with the α-peak obtained by dielectric relaxation spectroscopy. The results obtained by TSDC, XRD, and EDX analysis are in good agreement with the results of TSDC and charge transfer interface of the polymer matrix. [ABSTRACT FROM AUTHOR]

Salicylaldehyde derived hexadentate Schiff base N,N'-Bis[2-salicylideneamino]ethane-1,2-diamine (TTS) and its complexes with Fe(III), Co(II) and Cu(II) metal ions have been prepared and characterised by elemental analysis, UVvisible, IR, 1H NMR, EPR spectral analysis, mass spectrometry and XRD method. In vitro antibacterial activity of the Schiff base and its metal complexes against Gram positive bacterial strains Staphylococus aureus, Bacillus subtilis and Gram negative bacterial strains Enterobacter, Escherichia coli has revealed that the metal complexes are more active to the bacterial strains as compared to that of the Schiff base. The Co-TTS has the highest antibacterial activity against Escherichia coli, while the Fe-TTS complex is highly active against Enterobacter, Staphylococcus aureus and Bacillus subtilis.

Abstract Assam is very rich in plant biodiversity as well as in ethnic diversity and has a great traditional knowledge base in plant resources. It is inhabited by the largest number of tribes and they lead an intricate life totally dependent on forest plants. The Mising is the major section and second largest tribal community of Assam and have a rich tradition of religion and culture. Their religious practices and beliefs are based on supernaturalism. A study of the plants related to magico religious beliefs in Dobur Uie of Mising is carried out. The results revealed the use of 30 plants belonging to 23 families. All plant species are used both in religious purpose as well as in the treatment of different ailments. Details of the uses of plants and conservational practices employed in Dobur Uie are provided. Our findings on the use of plants in Dobur Uie ritual reflect that some plants are facing problems for survival and they need urgent conservation before their elimination. Because this elimination may threat the rich tradition of Mising culture. Most of the plants that are domesticated for different rituals are almost same in all Mising populated areas.

Abstract Background Among the naturally occurring compounds, turmeric from the dried rhizome of the plant Curcuma longa has long been used extensively as a condiment and a household remedy all over Southeast Asia. Turmeric contains essential oil, yellow pigments (curcuminoids), starch and oleoresin. The present study was designed for investigating the neuroprotective efficacy and the time window for effective therapeutic use of Curcuma oil (C. oil). Method In the present study, the effect of post ischemic treatment of C.oil after ischemia induced by occlusion of the middle cerebral artery in the rat was observed. C.oil (500 mg/kg body wt) was given 4 hrs post ischemia. The significant effect on lesion size as visualized by using diffusion-weighted magnetic resonance imaging and neuroscore was still evident when treatment was started 4 hours after insult. Animals were assessed for behavioral deficit scores after 5 and 24 hours of ischemia. Subsequently, the rats were sacrificed for evaluation of infarct and edema volumes and other parameters. Results C.oil ameliorated the ischemia induced neurological functional deficits and the infarct and edema volumes measured after 5 and 24 hrs of ischemia. After 24 hrs, immunohistochemical and Western blot analysis demonstrated that the expression of iNOS, cytochrome c and Bax/Bcl-2 were altered after the insult, and antagonized by treatment with C.oil. C.oil significantly reduced nitrosative stress, tended to correct the decreased mitochondrial membrane potential, and also affected caspase-3 activation finally apoptosis. Conclusion Here we demonstrated that iNOS-derived NO produced during ischemic injury was crucial for the up-regulation of ischemic injury targets. C.oil down-regulates these targets this coincided with an increased survival rate of neurons.

A hexadentate Schiff base N, N'-Bis[2-(salicylidene amino)]ethane-1,2-diamine (TTS) has been synthesized by condensation reaction of salicylaldehyde with triethylenetetramine (TETA) in ethanol and characterized by TLC, M.P., spectral analysis and mass spectrometry. This Schiff base has been used for liquid-liquid extraction and bulk liquid membrane transport studies of transition metal ions (Fe3+, Co2+, Ni2+, Cu2+, Zn2+). The effect of metal ion concentration variation on extraction and transport is studied. The observed trend for extraction and transport of transition metal ions using Schiff base (TTS) is Cu2+> Fe3+> Co2+> Zn2+ ᴝ Ni2+ and Zn2+> Fe3+> Ni2+> Co2+ ᴝ Cu2+ respectively. The result of extraction study shows that TTS has highest extraction efficiency for Cu2+ metal ions followed by Fe3+, Co2+, Zn2+ and Ni2+ metal ions. This can be explained on the basis of cavity fit concept, size and charge density of metal ions and Pearson's HSAB concept. The results of extraction and transport studies reveals that in general the TTS has high extraction efficiency as compared to that of transport, this may be due to TTS adopts a cis conformation with both arms at the same side, which leads to a better predisposed ionophore for metal complexation by bringing the nitrogen and oxygen donor sets closer proximity and form pseudo cavity.

The time kinetics of hot carrier degradation (HCD) is modeled using a reaction diffusion drift (RDD) framework. It is incorporated into Sentaurus Device TCAD and validated using conduction mode HCD data in n- and p-channel MOSFETs and FinFETs. RDD-enabled TCAD calculates carrier-energy-initiated generation of interface traps (Δ NIT) and the impact of the resulting localized charges on device parametric drift. HCD at various gate (VG) and drain (VD) biases spanning various modes (VG ≤ and > VD) are simulated for low stress VD (< 3 V). The self-heating (SH)-effect-induced temperature (T) increase is invoked for FinFETs. Data from various experiments are analyzed and a wide range of power-law time kinetics slope (n) is explained.

Objectives: Stroke is a leading cause of death and disability worldwide with limited therapeutic interventions. The current study explored proton nuclear magnetic resonance spectroscopy (1H NMR)‐based metabolomic approach to elucidate the effect of lercanidipine on neurometabolic alterations in transient model of ischaemic stroke in rats. Methods: In the present investigation, male Wistar rats were subjected to middle cerebral artery occlusion (MCAo) for 2 h followed by reperfusion using intraluminal filament method. Rats were randomly divided into three groups as vehicle‐treated sham control, vehicle‐treated MCAo control and lercanidipine‐treated MCAo. Vehicle or lercanidipine (0.5 mg/kg, i.p.) was administered 120 min post‐reperfusion. The rat brain cortex tissues were isolated 24 h post‐MCAo and were investigated by 1H NMR spectroscopy through perchloric extraction method. Key findings: A total of 23 metabolites were altered significantly after cerebral ischaemic–reperfusion injury in MCAo control as compared to sham control rats. Lercanidipine significantly reduced the levels of valine, alanine, lactate, acetate and tyrosine, while N‐acetylaspartate, glutamate, glutamine, aspartate, creatine/phosphocreatine, choline, glycerophosphorylcholine, taurine, myo‐inositol and adenosine di‐phosphate were elevated as compared to MCAo control. Conclusions: Present study illustrates effect of lercanidipine on neurometabolic alterations which might be mediated through its antioxidant, anti‐inflammatory, vasodilatory and anti‐apoptotic property in MCAo model of stroke.

Lymphomas constitute the third most common neoplasm in head and neck region arising from the lymphoreticular system. Malignant lymphomas are divided into Hodgkin's disease and non-Hodgkin's lymphoma (NHL). NHL comprises approximately 5% of head and neck malignancies and displays a wide range of appearances comparable with Hodgkin's disease. Hodgkin's and non-Hodgkin's lymphomas are seen in the head and neck region, but extranodal disease, with or without lymph node involvement, is more common among NHL patients. Extranodal involvement includes the areas such as Waldeyer's ring (i.e., the tonsils, pharynx, and base of the tongue), salivary glands, orbit, paranasal sinuses, and thyroid glands. There are several classification systems for categorizing NHL out of which WHO classification for lymphoid neoplasms is mostly followed. This review describes the pathogenesis of NHL and explains some of the important NHL (Marginal zone B-cell Lymphoma, follicular lymphoma, mantle cell lymphoma). [ABSTRACT FROM AUTHOR]
