Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrine-metabolic disorder affecting females across the lifespan. Eating disorders (EDs) are psychiatric conditions that may impact the development of PCOS and comorbidities including obesity, metabolic syndrome, and type 2 diabetes. The aim of this scoping review was to determine the prevalence of EDs and disordered eating, and to review the etiology of EDs in PCOS. The review was conducted using search terms addressing PCOS, EDs, and disordered eating in databases, including PubMed, Scopus, PsycINFO, and CINAHL. Structured interviews, self-administered questionnaires, chart review, or self-reported diagnosis were used to identify EDs in 38 studies included in the review. The prevalence of any ED in those with PCOS ranged from 0% to 62%. Those with PCOS were 3-6-fold more likely to have an ED and higher odds ratios (ORs) of an elevated ED score compared with controls. In those with PCOS, 30% had a higher OR of bulimia nervosa and binge ED was 3-fold higher compared with controls. Studies were limited on anorexia nervosa and other specified feeding or ED (such as night eating syndrome) and these were not reported to be higher in PCOS. To our knowledge, no studies reported on avoidant/restrictive food intake disorder, rumination disorder, or pica in PCOS. Studies showed strong associations between overweight, body dissatisfaction, and disordered eating in PCOS. The etiologic development of EDs in PCOS remains unclear; however, psychological, metabolic, hypothalamic, and genetic factors are implicated. The prevalence of any ED in PCOS varied because of the use of different diagnostic and screening tools. Screening of all individuals with PCOS for EDs is recommended and high-quality studies on the prevalence, pathogenesis of specific EDs, relationship to comorbidities, and effective interventions to treat ED in those with PCOS are needed.

Abstract
Background Polycystic ovary syndrome (PCOS) is the most common metabolic-endocrine disorder impacting the health and quality of life of women over the lifespan. Evidence-based data on the scope of adverse health outcomes in those affected by PCOS is critical to improve healthcare and quality of life in this population. The aim of this study was to determine the prevalence of adverse health outcomes in those with PCOS compared to age-matched controls. Methods We conducted a retrospective observational case-control study in those diagnosed with PCOS and age-matched controls using the Alberta Health Services Health Analytics database and the International Classification of Diseases, for the period from 2002-2018 in Alberta, Canada. Results The cohort consisted of n = 16,531 exposed PCOS cases and n = 49,335 age-matched un-exposed controls. The prevalences of hypertension, renal disease, gastrointestinal disease, eating disorders, mental illness, depression-anxiety, rheumatoid arthritis, respiratory infections, and all malignancies were 20%-40% (P < 0.0001) higher in those with PCOS, compared to controls. The prevalence of obesity, dyslipidemia, nonalcoholic fatty liver disease, and type 2 diabetes was 2-3 fold higher in those with PCOS (P < 0.001). Cardiovascular, cerebrovascular, and peripheral vascular disease were 30%-50% higher, and they occurred 3-4 years earlier in those with PCOS (P < 0.0001); a 2-fold higher prevalence of dementia occurred in those with PCOS, compared to controls. Conclusion These findings provide evidence that PCOS is associated with a higher prevalence of morbidities over the lifespan, and the potential scope of the healthcare burden in women affected by PCOS.

Abstract
BACKGROUND Polycystic Ovary Syndrome (PCOS) is the most common endocrine-metabolic disorder affecting health and quality of life of those affected across the lifespan. We currently have limited evidence-based data on the experience of those living with PCOS in the health care system including diagnosis, health concerns and disease management. The aim of this study was to assess the perceptions of health status, health care experience and disease management support in those affected by PCOS in Alberta, Canada. METHODS An online questionnaire was completed via REDCap by individuals self-reporting a diagnosis of PCOS. Question categories included demographics, symptoms of PCOS and time to confirm a diagnosis, follow-up care, health concerns, and information resources. Descriptive statistics were used and thematic analyses was applied to open-response questions. RESULTS Responses from 194 participants living in Canada (93% in Alberta) were included. The average age was 34 ± 8 years and BMI was 35 ± 9. Menstrual irregularity was identified in 84% of respondents as the first symptom noticed and the primary reason for seeking a medical consultation. A PCOS diagnosis occurred on average 4.3 years following awareness of first symptoms and required consultation with more than one primary care provider for 57% of respondents. Half (53%) of respondents reported not receiving a referral to specialists for follow-up care and 70% were not informed about long-term health morbidity such as diabetes or cardiovascular disease. Most respondents (82%) did their own research about PCOS using on-line sources, academic literature and advice from peer support. The participant themes from open questions for improving health care included more resources and support, increased and reliable information, better education and training for clinicians, timely diagnosis, prompt referrals to specialists, and generally more compassion and empathy to the challenges faced by those managing their disease. CONCLUSION Our findings highlight the health concerns and challenges in health care for those with PCOS. In Alberta, Canada we have identified major gaps in health care including a timely diagnosis, follow up care and supports, and multidisciplinary care. This evidence-based data can be used to inform development of pathways to improve the health care experience in those affected by PCOS.

Abstract
INTRODUCTION Despite a high prevalence of retained bullet fragments (RBFs) after firearm related injury (FRI) there is limited data on the full spectrum of their consequences, particularly the psychological impacts on those injured. Further, the experiences of FRI survivors with RBFs are missing from existing literature. The objective of this study was to explore the psychological impacts of RBFs on individuals who have experienced recent FRI. METHODS Adult (18-65 years) survivors of FRI with radiographically confirmed RBFs were purposively selected from an urban Level 1 trauma center in Atlanta, Georgia, to participate in an in-depth interview. Interviews were conducted between March 2019 and February 2020. Thematic analysis was used to identify a range of psychological effects from RBFs. RESULTS Interviews from 24 FRI survivors were analyzed: the majority of participants were Black males (N = 22, 92%) with a mean age of 32 years whose FRI occurred ∼8.6 months prior to data collection. The psychological effects of RBFs were grouped into four categories: physical health (eg, pain, limited mobility), emotional well-being (eg, anger, fear), social isolation, and occupational welfare (eg, disability leading to inability to work). A range of coping mechanisms were also identified. CONCLUSION Survivors of FRI with RBFs experience a range of psychological impacts that are far-reaching and affect daily activities, mobility, pain and emotional wellbeing. Study results indicate a need for enhanced resources to support those with RBFs. Further, changes to clinical protocols are warranted on removal of RBFs and communication about the effects of leaving RBFs in situ.

Abstract
Laser-direct-drive fusion target designs with solid deuterium-tritium (DT) fuel, a high-Z gradient-density pusher shell (GDPS), and a Au-coated foam layer have been investigated through both 1D and 2D radiation-hydrodynamic simulations. Compared with conventional low-Z ablators and DT-push-on-DT targets, these GDPS targets possess certain advantages of being instability-resistant implosions that can be high adiabat (α≥8) and low hot-spot and pusher-shell convergence (CR_{hs}≈22 and CR_{PS}≈17), and have a low implosion velocity (v_{imp}<3×10^{7}cm/s). Using symmetric drive with laser energies of 1.9 to 2.5MJ, 1D lilac simulations of these GDPS implosions can result in neutron yields corresponding to ≳50-MJ energy, even with reduced laser absorption due to the cross-beam energy transfer (CBET) effect. Two-dimensional draco simulations show that these GDPS targets can still ignite and deliver neutron yields from 4 to ∼10MJ even if CBET is present, while traditional DT-push-on-DT targets normally fail due to the CBET-induced reduction of ablation pressure. If CBET is mitigated, these GDPS targets are expected to produce neutron yields of >20MJ at a driven laser energy of ∼2MJ. The key factors behind the robust ignition and moderate energy gain of such GDPS implosions are as follows: (1) The high initial density of the high-Z pusher shell can be placed at a very high adiabat while the DT fuel is maintained at a relatively low-entropy state; therefore, such implosions can still provide enough compression ρR>1g/cm^{2} for sufficient confinement; (2) the high-Z layer significantly reduces heat-conduction loss from the hot spot since thermal conductivity scales as ∼1/Z; and (3) possible radiation trapping may offer an additional advantage for reducing energy loss from such high-Z targets.

Abstract
This present investigation aimed at characterizing the biochemical potential and kinetic study of the protease isolated from kitchen wastewater bacteria, P2S1An. The enzymatic activity was optimum when incubated for 96 h, at 30°C and pH 9.0. The enzymatic activity of the purified protease (PrA) was 10.47-folds that of crude protease (S1). PrA was about 35 kDa in molecular weight. The broad pH and thermal stability, chelators, surfactants and solvent tolerance, and favorable thermodynamics suggested the potentiality of the extracted protease PrA. Thermal activity and stability were enhanced in presence of 1-mM Ca2+ ion at high temperatures. The protease was a serine one as its activity was completely diminished in presence of 1-mM PMSF. The Vmax , Km , and Kcat /Km suggested stability and catalytic efficiency of the protease. PrA hydrolyzes fish protein with 26.61 ± 0.16% of peptide bond cleavage after 240 min, comparable to Alcalase 2.4L (27.13 ± 0.31%). PRACTITIONER POINTS: A serine alkaline protease PrA was extracted from kitchen wastewater bacteria Bacillus tropicus Y14. Protease PrA showed significant activity and stability in a wide temperature and pH range. Protease showed great stability towards additives like metal ions, solvents, surfactants, polyols, and inhibitors. Kinetic study showed that the protease PrA had a prominent affinity and catalytic efficiency for the substrates. PrA hydrolysed fish proteins into short bioactive peptides which signify its potential in the formation of functional food ingredients.

Abstract
Abstract
Background
PCOS is the most common metabolic-endocrine disorder impacting women over their lifespan. It is important to understand the scope of health outcomes that impact the health and quality of life of those with PCOS in order to improve clinical and patient-centered health care in this population.
Aim
The aim of this study was to determine the incidence of co-morbidities in PCOS compared to age matched controls. We hypothesised that women with PCOS would have increased incidence of co-morbidities.
Methods
A retrospective observational case-control study in those diagnosed with PCOS and age-matched controls (>12 yrs of age in a ratio of 1: 3) was undertaken using the Alberta Health Services Health Analytics database from 2002-2019 in Alberta, Canada. International classification codes (ICD9 and ICD10) were used to determine PCOS diagnosis including visits to a health care provider, Alberta ambulatory care reporting system and Discharge Abstract Data databases.
Results
The incidence of several co-morbidities were 20-40% higher in PCOS (n=16531) including hypertension, dyslipidemia, cardiovascular, cerebrovascular, gastrointestinal and renal disease, metabolic syndrome, eating disorders, mental illness, depression-anxiety, rheumatoid arthritis, respiratory infections and all cancers compared to controls (n=49335) (p<0. 0001). Overweight-obesity, non-alcoholic liver disease, Type 1 diabetes and Type 2 Diabetes had a 3-fold greater incidence in PCOS compared to controls (p<0. 0001).
Conclusion
These findings demonstrate PCOS is a major public health concern due to increased risk of co-morbidities and associated health-care costs. These findings provide evidence-based research to support the development of strategies to improve health care; screening, management and prevention of co-morbidities in high-risk PCOS populations.

Abstract
For brands, empathy can create a customer persona, which can help in effectively targeting their consumers. In terms of marketing, however, it means asking what customers truly value rather than what will sell. Moreover, by creating content that evokes empathy, consumers are more likely to take action – sharing, responding, and even prompting change within their communities. Nevertheless, why are brands suddenly realizing the power of empathy? This is because consumers today are not only interested in passively consuming content. Instead, they actively seek out content that prompts a change in themselves and the world around them. This need of the hour made the brand realize the power of effective communication and hence the rise of empathy as a useful marketing tool. The research used a qualitative approach to understand the effectiveness of Empathy marketing during the pandemic hit time. Focus Group Discussions were conducted to understand the importance and relevance of empathy-based communication. The findings established that this type of communication is useful and helps the consumer create a positive brand image and a recall, but this may not directly impact or lead to a purchase decision.

Abstract
Abstract
Objectives
Polycystic Ovarian Syndrome (PCOS), the most common endocrine-metabolic disorder in women, is associated with a higher incidence of obesity, metabolic syndrome, Type 2 Diabetes and Cardiovascular Disease. The recommended first line targets are diet, lifestyle and behaviour in managing body weight and adverse health outcomes. The objective of this study was to assess the health status, health care experience and supports related to nutrition and lifestyle in people with PCOS.
Methods
Respondents completed a retrospective survey online between Jan 2021-Jan 2022 and included Alberta (Canada) residents who self-reported a diagnosis of PCOS (n = 145). The survey was based on previous validated health and quality of life surveys in PCOS, expanded, and re-validated in PCOS patients and health care providers in Alberta. Themes of questions on diagnosis, referral to health care providers, health concerns, diet and nutrition were analyzed.
Results
The majority of respondents were aged 26 to 45 yrs of age (84%), self-reported overweight or obesity (96%) and were residents of Alberta for > 10 years (85%). In 34% of respondents a diagnosis of PCOS took > 2 years, and 60% reported visiting more than one healthcare provider before a final PCOS diagnosis. Many respondents (75%) were not informed of the health risks associated with PCOS. Following a PCOS diagnosis, 23% were diagnosed with high blood cholesterol and 25% with prediabetes or diabetes. Most respondents (> 80%) were not referred to a Registered Dietitian or other health care provider to manage PCOS symptoms and cardiometabolic risk factors. A lack of nutrition knowledge was reported as a major barrier to losing weight (38%), however the most common barriers cited were stress (75%) and negative feelings (60%). A priority recommendation by respondents to improve their health care included better education in diet-nutrition.
Conclusions
This data provides evidence for the need to develop preventative health care strategies to improve overall health, referral and access to diet-nutrition counseling in this high-risk PCOS population in Alberta, Canada.

Abstract
Context Adrenal insufficiency (AI) is an uncommon, life-threatening disorder requiring lifelong treatment with steroid therapy and special attention to prevent adrenal crisis. Little is known about the prevalence of AI in Canada or healthcare utilization rates by these patients. Objective We aimed to assess the prevalence and healthcare burden of AI in Alberta, Canada. Methods This study used a population-based, retrospective administrative health data approach to identify patients with a diagnosis of AI over a 5-year period and evaluated emergency and outpatient healthcare utilization rates, steroid dispense records, and visit reasons. Results The period prevalence of AI was 839 per million adults. Patients made an average of 2.3 and 17.8 visits per year in the emergency department and outpatient settings, respectively. This was 3 to 4 times as frequent as the average Albertan, and only 5% were coded as visits for AI. The majority of patients were dispensed glucocorticoid medications only. Conclusion The prevalence of AI in Alberta is higher than published data in other locations. The frequency of visits suggests a significant healthcare burden and emphasizes the need for a strong understanding of this condition across all clinical settings. Our most concerning finding is that 94.3% of visits were not labeled with AI, even though many of the top presenting complaints were consistent with adrenal crisis. Several data limitations were discovered that suggest improvements in the standardization of data submission and coding can expand the yield of future studies using this method.

Abstract
Lung cancer (both adenocarcinoma and squamous cell) progress through a series of pre-malignant histologic changes before the development of invasive disease. Each of these carcinogenic cascades is defined by genetic and epigenetic alterations in pulmonary epithelial cells. Additionally, alterations in the immune response, progenitor cell function, mutational burden, and microenvironmental mediated survival of mutated clones contribute to the risk of pre-malignant lesions progressing to cancer. Medical preventions studies have been completed and current and future trials are informed by the improved understanding of pre-malignancy. This will lead to precision chemoprevention trials based on lesional biology and histologic characteristics.

Abstract
A methodology has been developed for the complete compositional characterization of lithium titanate (LTO) using neutron activation, which is quite challenging and no literature report is available so far. The concept of thermal neutron induced in-situ chain reactions 6Li(n,α)3H and 16O(3H,n)18F has been used for the determination of Li and O through the measurement of 18F activity. The method is capable of analyzing Li and O in percentage level as reported in the present analysis of two types of lithium titanate samples. Spectroscopic interference of the elements which can directly or indirectly affect the outcome, were evaluated meticulously. Determination of Ti was carried out using fast neutron activation through the product isotopes like 47Sc, 48Sc, generated via (n,p) nuclear reactions. Fast neutron activation methodology seems to be advantageous for Ti determination over thermal neutron activation, as it offers self validation through different isotopes and multiple gamma lines.

Abstract
CONTEXT Women with polycystic ovary syndrome (PCOS) have increased incidence of atherogenic dyslipidemia and cardiovascular disease (CVD). Interventions targeting atherogenic dyslipidemia to reduce CVD risk are limited in women with PCOS. OBJECTIVE This pilot study was conducted to determine the effect of 12 weeks of high dose fish oil (FO), metformin, and FO as an adjunct to metformin (FO-metformin) therapy on fasting and nonfasting plasma lipids and ApoB-remnants in young women with the metabolic syndrome (MetS) and PCOS. METHODS In this open-label parallel pilot trial, women with MetS and PCOS (18-30 years of age) were randomized into 1 of 3 interventions: (1) FO; (2) metformin; and (3) FO-metformin. Plasma lipids and ApoB (48 and 100)-lipoproteins and triglycerides (TG) were measured in the fasted and postprandial state following a high-fat meal at baseline and postintervention. RESULTS FO-metformin significantly lowered fasting plasma TG by >40% compared with FO and metformin treatments. Fasting plasma apoB48 was lowered 40% in FO-metformin and 15% in the FO groups from baseline to postintervention. ApoB48 area under the curve (ApoB48AUC), ApoB48 incremental AUC (ApoB48iAUC), ApoB100AUC, and ApoB100iAUC decreased in all groups from baseline to postintervention; however, these findings did not reach statistical significance. CONCLUSION The findings of this pilot trial show that high dose FO and FO-metformin combination therapy tend to lower fasting and postprandial plasma TG and ApoB-lipoprotein remnants compared with metformin; however, the study is limited by small sample size. These results may be clinically significant in individuals with PCOS for management of atherogenic dyslipidemia.

Abstract
Background There is a growing interest in the role of brain-derived neurotrophic factor (BDNF) in major depressive disorder (MDD). BDNF potentially exhibits opposite effects in the pathways linked to anhedonia and reward learning on the one hand and cognitive performance, on the other hand. However, the epigenetic mechanisms behind this remain unknown. In the present study, we aimed to investigate the interplay of DNA methylation of different BDNF exons and the common Val66Met polymorphism on anhedonia, reward learning and cognitive performance in MDD. Methods We recruited 80 depressed patients and 58 age- and gender-matched healthy controls. Participants underwent clinical assessment including neuropsychological testing and a probabilistic reward task to assess reward learning. Val66Met polymorphism and DNA methylation of BDNF promoters I, IV and exon IX were assessed from whole blood derived DNA, using pyrosequencing. Results BDNF promoter I methylation was lower in MDD patients (p = 0.042) and was negatively associated with self-reported anhedonia. In depressed patients, both Val66Met polymorphism and DNA methylation of promoter I were significantly associated with reward bias (p < 0.050 and p = 0.040, respectively), without an interaction effect. On the other hand, methylation of exon IX had a negative impact on executive functioning (p = 0.002) and mediated the effect of Val66Met on this outcome in patients with MDD. Conclusions Our results provide the first evidence of Val66Met susceptibility to differential epigenetic regulation of BDNF exons in reward learning and executive functioning in MDD, which needs to be further explored.

Abstract
Healthy food trend is becoming popular these days fueling search for ingredients empowered by pharma-nutritional benefits. In contrast, numerous wild-growing mushrooms are traditionally cherished as health promoting gastronomies in India; although credibility of their effects has so far been limited. Hence the present study aimed to unveil a unique tribal cuisine, Russula alatoreticula, with nutritional, chemical and pharmacological relevance. The outcome demonstrated an excellent alimentary composition with carbohydrate and protein as prominent macronutrients in contrast to fat providing oleic acid (36.66%), linoleic acid (16.84%), palmitic acid (16.01%) and stearic acid (15.31%) indicative of profitable nutritive account. Conversely, ethanolic fraction enriched with phenolics (pyrogallol > cinnamic acid) presented effective antioxidant property in terms of radical scavenging, Fe2+ chelating and reducing power with EC50 ranging from 785 to 2500 μg/ml. Remarkable antibacterial activity was also noted against the tested microorganisms (MIC of 72.5-1560 μg/ml) preferentially targeting Gram-positive one. Besides treatment of the preparation rendered Hep3B proliferation as evident by phenotypic changes, cell cycle interference, reactive oxygen species generation, mitochondrial membrane potential reduction, DNA fragmentation, change in Bax/Bcl2 ratio and activation of caspase9 signifying induction of intrinsic mitochondrial pathway. Thus the study represents R. alatoreticula as a value-added bio-resource that could be featured in food and pharmaceutical industries for betterment of humankind.

Abstract
Background: Polycystic ovary syndrome (PCOS) is highly associated with the metabolic syndrome (MetS): obesity, insulin resistance and atherogenic dyslipidemia. Women with PCOS-MetS are at higher risk of developing ischemic cardiovascular disease (CVD) and Type-2 Diabetes. First-line intervention in PCOS-MetS includes targeting diet and lifestyle, and metformin is commonly prescribed to treat insulin resistance, however these interventions have shown limited effectiveness to improve dyslipidemia. At present there are limited safe and efficious options to target atherogenic dyslipidemia in young women with PCOS. Fish oil (FO) and Icosapentyl ethyl supplementation have been shown to reduce fasting TG, apoB and to improve ischemic CVD outcomes. The efficacy of FO or as an adjunct therapy to metformin to improve ApoB-remnant lipemia in PCOS-MetS is unknown. The aim of this pilot study was to determine the effect of metformin, FO and FO-metformin combination treatment on fasting and non-fasting plasma TG and apoB-remnant lipoprotein metabolism in patients with PCOS-MetS. Methods: Participants diagnosed with PCOS aged 18-30yrs received dietary counselling and were randomly assigned to receive FO (n=8), metformin (n=7) or FO-metformin (n=12) treatment for 12 wks. Plasma lipids (TG and cholesterol), ApoB48 and ApoB100 lipoprotein metabolism were assessed in the fasting and non-fasting state using a standardized high-fat meal test. Results: At baseline, the fasting plasma TG, ApoB48 and ApoB100 was 238.0 ± 21.0 mg/dL, 9.00 ± 1.12 ug/ml and 290 ± 18.00 mg/dL. FO and FO-metformin decreased fasting plasma TG by 10% and 30% compared to the metformin treatment group (7%). Fasting ApoB48 was reduced 45%, 16% and 19% in FO-metformin, FO and metformin treatment groups, respectively. Non-fasting plasma TG and apoB48 lipoprotein area under the curve were reduced by 30% in the FO-metformin treatment group. Conclusion: These pilot findings demonstrate FO-metformin adjunct therapy may have greater efficacy to improve atherogenic apoB-dyslipidemia compared to metformin or FO alone in high-risk patients with PCOS-MetS. A larger clinical trial is warranted to determine the long term effects of FO-metformin intervention on apoB-dyslipidemia and atherosclerotic cardiovascular disease indices.

Abstract
Introduction: In polycystic ovary syndrome (PCOS) a high plasma level of androgens has been correlated with an adverse plasma lipid profile. At present we do not know the physiological or mechanistic pathways of how androgens regulate lipid metabolism under control or PCOS conditions. We have shown flutamide, an androgen receptor (AR) inhibitor, reduces the plasma concentration of triglycerides (TG) and apoB-lipoproteins, and intestinal secretion of TG. Aim: The aim of this study was to determine the direct physiological and mechanistic effects of androgens, Testosterone (T) and dihydrotestosterone (DHT), on lipid metabolism using a PCOS-prone rodent model. Methods: Control and PCOS-prone animals were administered vehicle, T or DHT for 7 days. PCOS-prone animals also present with the Metabolic Syndrome (MetS). Following treatment animals underwent a mesenteric lymphatic cannulation procedure to determine effects on intestinal chylomicron (CM-apoB48) and lipid secretion, and absorption using radiolabelled [³H]-cholesterol and [14C]-palmitic acid. Results: Plasma LDL-C was increased with DHT treatment in control animals, and with both T & DHT treatment in PCOS. Intestinal absorption of TG and cholesterol were increased in T and DHT treated PCOS animals but not control animals. Whereas DHT reduced intestinal CM-apoB48 secretion in both control and PCOS groups. These effects were associated with changes in genes and protein expression in lipogenic (SREBP1a/c&2, SREBP1c, SREBP-2, ACC) and steroidogenic pathways (AR, ER and SRDA51) in the liver and intestine. Conclusion: These results demonstrate androgens modulate lipid metabolism and absorption. T and DHT differentially affect intestinal chylomicron secretion and lipid absorption in PCOS-MetS and control conditions. In conclusion, these results suggest that androgens may directly cause or exacerbate lipid and lipoprotein metabolism in conditions of hyperandrogenemia and the MetS.

Abstract
Rice bran oil fatty acid distillate (RBOFAD) is an important by-product obtained from the physical refining process. This fatty acid distillate contains high a amount of Unsaponifiable Matter (γ-oryzanol 3.27 gm/100gm UM; total tocopherol 10.93 mg/100 g UM; total phytosterol 21.81 g/100g UM; squalene 1.15 g/100 g UM and total fatty alcohol 73.34 g/100 g UM) and free fatty acids. Antioxidant-rich Oleogels were obtained from rice bran wax (RBW), rice bran oil fatty acid distillate (RBOFAD) and refined rice bran oil. The main objective of this study was to utilize the antioxidant-rich unsaponifiable matter of RBOFAD (UMRBOFAD) as an organogelator along with rice bran wax, which also acts as a good organogelator. Antioxidant-rich oleogel was prepared using UMRBFAD, ethylcellulose (EC) and RBW at 2%, 2%, 3% on weight basis, respectively, in refined rice bran oil and this antioxidant-rich oleogel was compared with rice bran oil oleogel using RBW at 7% on weight basis of rice bran oil. These oleogels were evaluated using a combination of techniques such as differential scanning calorimetry (DSC), polarized light microscopy (PLM), Viscosity, synchrotron radiation X-ray diffraction (SR-XRD) and FTIR Spectroscopy. The differential scanning calorimetry (DSC) measured the thermal properties of rice bran oil oleogel and high antioxidant-rich oleogel. Polarized light microscopy images revealed needle-like crystals for RBW. SR-XRD measurements were used for clarification of the crystal structures of the building blocks of these oleogels. The antioxidant activities of oleogels were evaluated involving DPPH and ABTS assays.

Abstract
We study the motion of Zn^{2+} in the presence of ubiquitin by all-atom molecular-dynamics simulations. We observe that unlike normal diffusive liquid, metal ions show an exponential tail in the self-van Hove function (self-vHf). Moreover, the metal ions are trapped strongly by acidic residues which form a binding pocket over the protein surface. The exponential tail disappears by mutation of trapping residues, suggesting that the tail appears due to trapped motion of the ions. The mean-squared displacements, however, in all the cases show linear dependence on time. Our model establishes that ligand binding generically results in an exponential tail of self-vHf. The self-vHf may give an approach to find binding pockets over a protein surface.

Abstract
Bluetongue (BT) is an economically important, infectious and non-contagious disease of ruminant animals. BT disease is caused by bluetongue virus (BTV) of the genus Orbivirus (the family Reoviridae). BTV is transmitted by certain species of biting midges of the genus Culicoides. Although originally BT was restricted to African continent, now it is present in all the continents except Antarctica. Conventional BT vaccines such as live attenuated and inactivated vaccines showed different degree of success in BT control. However, conventional vaccines have certain disadvantages of reversion to virulent strain and frequent booster dose requirement. Several BT outbreaks in India and the rest of the world open a new insight for development of better vaccines. The development in molecular biology techniques allowed the development and validation of several modern vaccines such as subunit vaccine, recombinant vector vaccine, disabled infections single cycle (DISC) vaccine, differentiating infected from vaccinated animals (DIVA) approach etc. Most of these vaccines are considered as safer, having better protective immune response and provided cross-protective immunization against more than one serotype. Keywords: bluetongue virus; live vaccine; inactivated vaccine; DISC; recombinant vaccine.

Abstract
Conformational changes in bio-molecular systems are fundamental to several biological processes. It is important to study changes in responses of underlying microscopic variables, like dihedral angles as conformational change takes place. We perform all-atom simulations and modelling via Langevin equation to illustrate the changes in structural and dynamic responses of dihedral angles of calcium ion binding residues of different proteins in metal ion free (apo) and bound (holo) states. The equilibrium distributions of dihedral angles in apo- and holo-states represent structural response. Our studies show the presence of dihedrals with multiple peaks (isomeric states) separated by barrier heights is more frequent in apo- than in holo-state. The relaxation time-scale of dihedral fluctuations is found to increase linearly with decreasing barrier height due to more frequent barrier re-crossing events. The slow kinetic response of the dihedrals also contributes to slowing down of macro-scale fluctuations, which may be useful to understand kinetics of various bio-molecular processes.

Abstract
Flagellin is a protein, responsible for virulent activities of bacteria. The host cell surface receptor protein TLR5 is known to interact with flagellin in order to activate immune response. However, the underlying microscopic details of this immune response are still elusive. In this study, we report on conformational stability of flagellin of two different organisms known as fliC and flaD in bilayer with reference to water. We find that both the flagellin is conformationally more stable in bilayer than in water. We also observe that fliC-TLR5 and flaD-TLR5 complexes are conformationally stable when the extracellular domain of the protein binds to conserved D1 domain of both fliC and flaD, although the binding interface between fliC-TLR5 and flaD-TLR5 is not identical. Our studies suggest that this might lead to differences in coreceptor bindings involved in immune response and thus have potential application in pharmaceutical developments.

Abstract
The objective of the present study was to synthesize ω-3 polyunsaturated fatty acid esters of lutein and to evaluate if esterification can stabilize the both bioactive molecules. Both ω-3 polyunsaturated fatty acid and lutein are prone towards auto-oxidation in their free form. Free lutein extracted from the marigold petals was enzymatically esterified using Candida antarctica NS435 Lipase B, with the ω-3 long-chain polyunsaturated fatty acids. The lutein esters were purified, characterized and finally assessed for their protective role against oxidative degradation in bulk fish oil matrix. The antioxidative effect of these esters was compared with commercial antioxidants of natural origin, i.e., α-tocopherol and a synthetic antioxidant, i.e., tert-butylhydroquinone, at a dosage of 200 mg/L. Both free lutein and lutein-polyunsaturated fatty acid ester had significantly promoted the oxidative stability of bulk fish oil. But based on dose-response relationship, lutein-polyunsaturated fatty acid ester was found to be more efficient than free lutein, in protecting fish oil from secondary oxidation, thereby augmenting their shelf life. Given the high nutraceutical value, potent antioxidative potential and organic origin, it is only relevant to incorporate lutein esters as natural preservative and stabilizers in edible oils.

Metformin is commonly used to treat insulin resistance-glucose intolerance, and flutamide, an androgen receptor (AR) antagonist, is used to target hyperandrogenemia and dyslipidemia. Currently, the physiological mechanism of action of these treatments on androgen, lipidogenic, and insulin signaling pathways remains unclear in PCOS. The aim of this study was to investigate the effects and mechanisms of action of metformin and flutamide on plasma lipid-apolipoprotein (Apo)B-lipoprotein and insulin-glucose metabolism, and endocrine-reproductive indices in a PCOS-prone MetS rodent model. PCOS-prone rodents were treated with metformin (300 mg/kg body wt), flutamide (30 mg/kg body wt), or metformin + flutamide combination treatment for 6 wk. Metformin was shown to improve fasting insulin and HOMA-IR, whereas flutamide and combination treatment were shown to reduce plasma triglycerides, ApoB48, and ApoB100, and this was associated with decreased intestinal secretion of ApoB48/triglyceride. Flutamide and metformin were shown to reduce plasma androgen indices and to improve ovarian primary and preovulatory follicle frequency. Metformin treatment increased hepatic estrogen receptor (ER)α, and metformin-flutamide decreased intestinal AR and increased ERα mRNA expression. Metformin-flutamide treatment upregulated hepatic and intestinal insulin signaling, including insulin receptor, MAPK1, and AKT2. In conclusion, cardiometabolic risk factors, in particular ApoB-hypertriglyceridemia, are independently modulated via the AR, and understanding the contribution of AR and insulin-signaling pathways further may facilitate the development of targeted interventions in high-risk women with PCOS and MetS.

Abstract
Anion binding CαNN motif is found in functionally important regions of protein structures. This motif based only on backbone atoms from three adjacent residues, recognizes free sulphate or phosphate ion as well as phosphate groups in nucleotides and in a variety of cofactors. The mode of anion recognition and microscopic picture of binding interaction remains unclear. Here we perform self-consistent quantum chemical calculations considering sulphate and phosphate bound CαNN motif fragments from crystal structures of functional proteins in order to figure out microscopic basis of anion recognition. Our calculations indicate that stability and preference of the anion in the motif depends on the sequence of the motif. The stabilization energy is larger in case of polar residue containing motif fragment. Nitrogen atom of the polar residue of motif mainly participates in the coordination at the lowest energy levels. Anion replacement decreases stabilization energy along with coordination between motif atoms and oxygen atoms of anion shifted to higher energies, suggesting preference of the motif residues to specific anion. Our analysis may be helpful to understand microscopic basis of interaction between proteins and ionic species.
