Abstract
Background This cross-sectional analytical study aimed to assess the level of knowledge on dietary management of chronic kidney disease (CKD) among patients undergoing hemodialysis in a tertiary care hospital in Puducherry, South India. Methodology The study was conducted among 86 inpatients diagnosed with CKD and undergoing hemodialysis in the dialysis unit. They were selected by simple random sampling. The self-administered, validated, self-structured questionnaire was used to collect the data. The study was conducted from May to September 2019. Descriptive statistics (frequency, percentage, mean, and standard deviation) and inferential statistics (chi-square) were used to find out the relationship between the level of knowledge and background variables using IBM SPSS Statistics for Windows, Version 25.0 (Released 2017; IBM Corp., Armonk, New York, United States). Results The findings indicated that the majority of patients were in the 20-30 age range (36, 41.9%), male (58, 67.4%), from nuclear families (58, 66.3%), with mixed dietary habits (60, 69.8%), and undergoing thrice-weekly hemodialysis (34, 53.5%). Additionally, 59 (68.6%) were hypertensive and 14 (16.3%) were diabetic. Most patients exhibited a moderate level of knowledge (74, 86%), while a small percentage had inadequate (6, 7%) and adequate (6, 7%) knowledge, with a mean (SD) value of 2.00 (0.376). The study identified statistically significant associations between knowledge levels and age, occupation, food habits, duration of dialysis, pre-existing co-morbid illnesses, and treatment of hemodialysis with a p-value <0.05. Conclusions In conclusion, this study highlights that the majority of the CKD patients undergoing hemodialysis exhibit moderately adequate knowledge of dietary management. However, a notable need remains for further education and support in this area. Addressing these knowledge gaps is crucial, as it can empower nursing students and healthcare professionals to educate these patients on their dietary needs effectively. By providing comprehensive education and support, we can enhance the quality of care and improve outcomes for hemodialysis patients.

Abstract
Abstract
Study question
Does the supplementation of vitamin B12 protect the spermatozoa against damage caused by the freeze-thaw process further improving the overall post-thaw survival and DNA integrity?
Summary answer
The antioxidant property of vitamin B12 protects the spermatozoa and improves the post thaw motility, vitality, and reduces DNA damage caused by freeze-thaw process.
What is known already
Cryopreservation of spermatozoa is an effective way of fertility preservation in humans, often used in Assisted Reproductive Technology(ART). Despite the refinement in cryopreservation, the salvage of post-thaw sperms remains poor. The reactive oxygen species(ROS), that is formed as a result of freeze-thaw process is known to decrease the motility, plasma membrane integrity and increase the DNA fragmentation. Most vitamins have antioxidant properties, that protect the mammalian cells from oxidative stress one such vitamin is cyanocobalamin(vitamin B12). Vitamin B12 modulates oxidative stress through methionine synthase activity and also acts as a scavenger of ROS. Thus protecting the DNA against free radicals.
Study design, size, duration
This prospective observational study was performed for a period of 6 months in 111 men, who attended the fertility clinic. The study population included all semen samples except men with azoospermia, surgically retrieved samples and men on vitamin supplements. The study population contained men ageing between 21-40 years.
Participants/materials, setting, methods
Semen samples were analysed according to WHO 5th edition and were assessed for DNA fragmentation index (DFI) using sperm chromatin dispersion assay (SCD). The ejaculates were split into two as group A: semen samples with equal amount of cryoprotectant and group B: semen samples with equal amount of cryoprotectant supplemented with Vitamin B12 (2mg/ml). They were frozen for a minimum of 24 hrs. Post-thaw motility, vitality and DFI were assessed and compared.
Main results and the role of chance
The mean age of patients in our study was 34.26±4.7yrs. 58.5% of the study population had primary infertility. 37.8% of the study population had male factor infertility, 32.4% had oligoasthenoteratozoospermia(OAT), 31.1% had normozoospermia 16.2% had asthenoteratozoospermia, 13.5% had teratozoospermia, 3.6% had oligozoospermia and rest 2.7% had asthenozoospermia.
There was an overall increase in post thaw motility (41.59±18.09 vs 32.3±18.8,p=0.0005), progressive motility (21.54±13.02 vs 15.91±11.80,p=0.0005), vitality (57.14±15.09 vs 46.76±16.45,p=0.0005) and a significant decrease in DFI (26.69±10.03 vs 32.09±10.00,p=0.0005) in group B compared to group A.
Our study also demonstrated that, Normozoospermia patients had a significant increase in vitality (67.17±13.8 vs 58.51±12.0, p = 0.007) and lower DFI (22.68±9.3 vs 27.6±8.9, p = 0.02) in group B than in group A.
OAT patients had a significant increase in total motility (26.25±12.15 vs 15.7±11.4,p=0.0003), progressive motility (11.69±8.8 vs 6.14±5.8,p=0.0028), vitality (46.06±11.34 vs 34.31±12.99,p=0.0001) and significantly lower DFI (30.22±9.87 vs 36.08±9.7,p=0.012) in group B.
Teratozoospermia patients showed significant increase in progressive motility in group B (27.87±8.81 vs 19.33±10.69,p=0.02) and
Asthenoteratozoospermia patients showed significant increase in total motility (40.72± 13.14 vs 30.89±13.06,p=0.02) and vitality (54.39±12.28 vs 43.78±14.14,p=0.02) in group B.
However, in asthenozoospermic patients the parameters were comparable in both the groups.
Limitations, reasons for caution
Due to ethical reasons the samples were not used for in vitro procedures such as intrauterine insemination(IUI), in vitro fertilization (IVF) and intracytoplasmic sperm injection(ICSI). Hence, no inference was obtained regarding the fertilization rates/ pregnancy rates.
Wider implications of the findings
Our study demonstrated that with supplementation of vitamin B12 the recovery rate significantly increased and also preserved the DNA content. Among the various categories, supplementation of vitamin B12 to OAT samples was more beneficial as it improved the overall viability of the sperms.

Abstract
Peroxisome proliferator activated receptors (PPARs) are group of nuclear receptors and the ligand-activated intracellular transcription factors that are known to play a key role in physiological processes such as cell metabolism, proliferation, differentiation, tissue remodeling, inflammation, and atherosclerosis. However, in the past two decades, many reports claim that PPARs also play an imperious role as a tumor suppressor. PPAR- gamma (PPARγ), one of the best-known from the family of PPARs, is known to express in colon, breast, bladder, lung, and prostate cancer cells. Its function in tumour cells includes the modulation of several pathways involved in multiplication and apoptosis. The ligands of PPARγ act by PPARγ dependent as well as independent pathways and are also found to regulate different inflammatory mediators and transcription factors in systemic inflammation and in tumor microenvironment. Both synthetic and natural ligands that are known to activate PPARγ, suppress the tumor cell growth and multiplication through the regulation of inflammatory pathways, as found out from different functional assays and animal studies. Cancer and inflammation are interconnected process that are now being targeted to achieve tumor suppression by decreasing the risks and burden posed by cancer cells. Therefore, PPARγ can serve as a promising target for development of clinical drug molecule attenuating the proliferation of cancer cells. In this perspective, this mini review highlights the PPARγ as a potential target for drug development aiming for anti-inflammatory and thereby suppressing tumors.

Abstract
The present study has planned to evaluate the neuroprotective activity of two novel glitazones in a neuroinflammatory rat model. Two novel glitazones were selected from an in-house virtual library of glitazones based on their docking scores against peroxisome proliferator-activated receptor-gamma (PPAR-γ) protein and other parameters studied in in silico computational studies. Initially, an acute oral toxicity study was carried out for glitazones in rats to assess the toxicity profile and to determine the therapeutic range for neuroprotective evaluation. Prior to induction of neuroinflammation, the treatments with glitazones (G1 and G2) and standard pioglitazone were made for four consecutive days to respective groups. On the fifth day, the neuroinflammation was induced by intracerebroventricular (ICV) administration of lipopolysaccharides (LPS) (2 μg/μl) using stereotaxic apparatus. After 7 days, the rats were subjected to behavioral assessment followed by neurobiochemical evaluation and histopathological studies. The pre-treatment with glitazones at two dose levels (15 and 30 mg/kg) has significantly reversed behavioral dysfunctions. Glitazones have shown significant reduction in the levels of LPO, NO, TNF-α, and IL-1β and also increased the levels of antioxidant enzymes such as SOD, CAT, and GSH in the brain of LPS-administered rats. The neuroprotection exhibited by two novel glitazones is comparable with standard pioglitazone. The PPAR-γ-dependent amelioration of cytokines and oxy-radicals released by novel glitazones during neuroinflammatory conditions may be attributed to the reversal of behavioral dysfunctions through preventing the degeneration of neurons in major regions of the brain.

Abstract
Peroxisome proliferator-activated receptor gamma (PPAR-γ) is one of the ligand-activated transcription factors which regulates a number of central events and considered as a promising target for various neurodegenerative disease conditions. Numerous reports implicate that PPAR-γ agonists have shown neuroprotective effects by regulating genes transcription associated with the pathogenesis of neurodegeneration. In regards, this review critically appraises the recent knowledge of PPAR-γ receptors in neuroprotection in order to hypothesize potential neuroprotective mechanism of PPAR-γ agonism in chronic neurological conditions. Of note, the PPAR-γ's interaction dynamics with PPAR-γ coactivator-1α (PGC-1α) has gained significant attention for neuroprotection. Likewise, a plethora of studies suggest that the PPAR-γ pathway can be actuated by the endogenous ligands present in the CNS and thus identification and development of novel agonist for the PPAR-γ receptor holds a vow to prevent neurodegeneration. Together, the critical insights of this review enlighten the translational possibilities of developing novel neuroprotective therapeutics targeting PPAR-γ for various neurodegenerative disease conditions.

Abstract
Foot-and-mouth disease virus (FMDV) samples transported to the laboratory from far and inaccessible areas for diagnosis and identification of FMDV pose a major problem in a tropical country like India, where wide fluctuation of temperature over a large geographical area is common. Inadequate storage methods lead to spoilage of FMDV samples collected from clinically positive animals in the field. Such samples are declared as non-typeable by the typing laboratories with the consequent loss of valuable epidemiological data. In this study, an attempt was made to evaluate the robustness of Flinders Technology Associates (FTA) cards for storage and transportation of FMDV samples in different climatic conditions which will be useful for FMDV surveillance. Simulation transport studies were conducted using FTA impregnated FMDV samples during post-monsoon (September-October 2010) and summer season (May-June 2012). FMDV genome or serotype could be identified from the FTA cards after the simulation transport studies with varying temperature (22-45°C) and relative humidity (20-100%). The stability of the viral RNA, the absence of infectivity and ease of processing the sample for molecular methods make the FTA cards an useful option for transport of FMDV genome for identification and type determination. The method can be used routinely for FMDV research as it is economical and the cards can be transported easily in envelopes by regular courier/postal systems. The absence of live virus in FTA card can be viewed as an advantage as it restricts the risk of transmission of live virus.

Abstract
Foot-and-mouth disease (FMD) virus serotype O is the most common cause of FMD outbreaks in India and three of the six lineages that have been described are most frequently detected, namely Ind2001, PanAsia and PanAsia 2. We report the full capsid sequence of 21 serotype O viruses isolated from India between 2002 and 2012. All these viruses belong to the Middle East-South Asia (ME-SA) topotype. The serological cross-reactivity of a bovine post-vaccination serum pool raised against the current Indian vaccine strain, O/IND/R2/75,was tested by virus neutralisation test with the 23 Indian field isolates, revealing a good match between the vaccine and the field isolates. The cross reactivity of the O/IND/R2/75 vaccine with 19 field isolates from other countries (mainly from Asia and Africa) revealed a good match to 79% of the viruses indicating that the vaccine strain is broadly cross-reactive and could be used to control FMD in other countries. Comparison of the capsid sequences of the serologically non-matching isolates with the vaccine strain sequence identified substitutions in neutralising antigenic sites 1 and 2, which could explain the observed serological differences.

Abstract
This study investigated the transmission of foot-and-mouth disease virus (FMDV) from experimentally infected Indian buffalo to in-contact naïve and vaccinated cattle and buffalo. In each of six rooms, two donor buffalo that had been inoculated with FMDV were housed for five days with four recipient animals, comprising one vaccinated buffalo, one vaccinated calf, one unvaccinated buffalo and one unvaccinated calf. Vaccination was carried out with current Indian vaccine strain (O/IND/R2/75) and challenged on 28 days post-vaccination with an antigenically similar strain (O/HAS/34/05). All 12 donor buffalo and the six unvaccinated cattle and six unvaccinated calves developed clinical signs of foot-and-mouth disease (FMD). In contrast, all six vaccinated cattle (100%) and four out of six vaccinated buffalo (66.6%) were protected from disease but all became infected with FMDV. This confirms that buffalo have the potential to spread FMD by direct contact and that vaccination can block this spread. The numbers of animals in the study were too small to determine if the differences in clinical protection afforded by vaccination of cattle and buffalo are significant and warrant a different dose regime.

Abstract
NdVO4 nanoparticles are successfully synthesized by efficient sonochemical method using two different structural directing agents like CTAB and P123. The phase formation and functional group analysis are carried out using X-ray diffraction (XRD) and fourier transform infra red (FT-IR) spectra, respectively. Using Scherrer equation the calculated grain sizes are 27 nm, 24 nm and 20 nm corresponding to NdVO4 synthesized by without surfactant, with CTAB and P123, respectively. The TEM images revealed that the shape of NdVO4 particles is rice-like and rod shaped particles while using CTAB and P123 as surfactants. The growth mechanism of NdVO4 nanoparticles is elucidated with the aid of TEM analysis. From electrical analysis, the conductivity of NdVO4 nanoparticles synthesized without surfactant showed a higher conductivity of 5.5703 × 10(-6) S cm(-1). The conductivity of the material depends on grain size and increased with increase in grain size due to the grain size effect. The magnetic measurements indicated the paramagnetic behavior of NdVO4 nanoparticles.

Abstract
Foot-and-mouth disease (FMD) is an economically significant viral disease that rampage dairy and other livestock industries in many countries. The disease is being controlled by the use of an inactivated vaccine. However, a recombinant marker vaccine, which avoids the use of live virus, may be an option for the unambiguous differentiation of infected animals from vaccinated animals. A recombinant baculovirus clone containing P1-2A-3C coding sequences of foot-and-mouth disease virus (FMDV) serotype O(1) Manisa was generated. The FMDV structural proteins along with the 3C protease were expressed in Sf9 cells and the generation of virus like particles (VLP) was studied. The recombinant protein was formulated as vaccine using an oil adjuvant, ISA 206 and potency of the vaccine was tested in cattle. The vaccine had a potency value (PD(50)) of 5.01 and most of the vaccinated animals exhibited neutralizing antibody titers after two immunizations.

Abstract
A one-step, real-time reverse transcription-loop-mediated isothermal amplification assay (RT-LAMP) for rapid detection and serotyping of Indian foot-and-mouth disease virus (FMDV) is described. The RT-LAMP assay was found to be 10(3)-10(5) fold more sensitive in comparison with RT-PCR, with a detection limit ranging from 10(-3) to 10(-5) TCID(50) of virus samples of all three serotypes. The RT-LAMP assay and qRT-PCR could detect 100 percent of clinical samples of three serotypes, whereas the RT-PCR detected 69.7% of type O, 58.1% of type A and 60.0% of Asia 1 samples. The qRT-PCR has the same sensitivity as the RT-LAMP. The assay conditions with absence of cross reactivity within the three serotypes of FMDV and FMDV negative samples were established. The RT-LAMP assay could detect 100% of samples stored in FTA(®) cards. In comparison with the performance of the RT-PCR; the RT-LAMP appears to be more sensitive, rapid and specific, with the potential for use as a point-of-care (POC) test, especially in developing countries. The use of FTA(®) cards for the preservation of RNA samples coupled with the RT-LAMP assay for the identification of serotypes may help in achieving improved FMDV serotype identification both in the field and in the laboratory.

Abstract
Small ruminants play an important role in the epidemiology of Foot-and-Mouth Disease (FMD). Small ruminants are vaccinated with one-half or one-third of cattle dose of oil-based or aqueous vaccines respectively. The extinction antigen payload in vaccine for protection in small ruminants is poorly studied. FMD seronegative Nellore sheep (n=30) and Osmanabadi goats (n=30) were vaccinated with different payloads of O(1) Manisa vaccine (0.45-5 μg). Vaccinated and sero-negative unvaccinated sheep (n=6) and goats (n=6) were challenged intradermally into the coronary band with O(1) Manisa virus. The sheep and goats were monitored for signs of FMD and samples were collected for measuring viraemia and virus associated with nasal swabs and probang samples. Clotted blood was collected for serology. Vaccines containing antigen payload up to 0.94 μg protected sheep and goats against challenge. Sheep and goats vaccinated with 0.45 μg antigen payload were poorly protected against challenge. An antigen payload of 0.94 μg was sufficient to offer complete protection and also absence of carrier status. Sheep and goats with no vaccination or with poor sero conversion to vaccination showed sub-clinical infection and became carriers. The results of the study suggest that vaccination offers protection from clinical disease even at a low payload of 0.94 μg and hence one-half of cattle dose of the oil-based vaccine formulations is sufficient to induce protective immune response in sheep and goats. Since no live virus could be isolated after 5 days post challenge from the nasal swab or probang samples even though viral RNA was detected, the risk of these animals transmitting disease was probably very low.

Abstract
Many traditional treatments have been recommended in the alternative system of medicine for diabetes mellitus. However, the mode of action of most of the herbals used has not been defined. It has been reported that sex hormones are important regulators of insulin-mediated events in skeletal muscles. In view of this, a novel herbal preparation containing antidiabetic and aphrodisiac plants was used in the present study. Adult male albino rats were divided into following groups after induction of diabetes. Rats were given an intraperitoneal (i.p.) injection of streptozotocin (STZ), at a dose of 65 mg/kg body weight after overnight fasting, to induce diabetic state with blood glucose levels >250 mg/dL. Group 1-Control rats treated with single i.p. injection of vehicle, Group 2-Rats treated with polyherbal preparation (PHP; 500 mg/kg body weight by oral intubation, morning and evening for 30 days), Group 3-STZ-diabetic rats treated orally with equal volumes of vehicle (water) alone and Group 4-STZ-diabetic rats treated with PHP after 10 days of diabetic induction. STZ-diabetes decreased the body weight, serum insulin level and glucose oxidation in liver and skeletal muscles but increased the fasting blood glucose level. After polyherbal treatment, body weight and glucose oxidation were completely restored to control level while serum insulin level was restored partially and the glucose tolerance was significantly improved. There was a significant decrease in total haemoglobin (Hb) level of diabetic rats when compared to control but polyherbal treatment significantly improved the same. However, the other parameters studied (red blood cell [RBC], white blood corpuscle [WBC], packed cell volume [PCV], mean corpuscular volume [MCV] and mean corpuscular haemoglobin [MCH]) were unaltered. In conclusion, the anti-diabetic properties of PHP appear to be mediated through pancreatic beta-cell regeneration, resulting in maintenance of optimal blood glucose and its oxidation in liver and skeletal muscles.

Abstract
An outbreak of pasteurellosis with high mortality was recorded in indigenous pigs in India. The presence of Pasteurella multocida in samples collected from dead pigs was detected by smear examination and isolation, and later by P. multocida specific polymerase chain reaction (PM-PCR). P. multocida was detected in all the samples collected from dead pigs, with nine strains ultimately isolated. All the isolates were positive by PM-PCR. Six isolates showed CAPA and three were of CAPD capsular types. All the isolates were negative for toxigenic gene (toxA). The isolates were sensitive to oxytetracycline, doxycycline, gentamycin, erythromycin, ampicillin, amoxycillin, chloramphenicol and enrofloxacin and resistant to sulphadiazine and cloxacillin. The PCR assays used in this study have been shown to be useful diagnostic tools for P. multocida detection and characterization.
