Mycobacterium avium subsp. paratuberculosis, the causative agent of Johne’s
disease is a degenerative chronic granulomatous disease of bovines. In the present study,
quantitative real time polymerase chain reaction (qRT-PCR) using TaqMan chemistry targeting
the IS900 sequence of Mycobacterium avium subsp. paratuberculosis (MAP) was employed
for the molecular diagnosis of the disease in bovine faecal samples. Out of 200 bovine faecal
samples processed, 7 samples were tested as positive by IS900 qRT-PCR. The sensitivity limit
of detection of MAP DNA in faecal samples by qRT-PCR TaqMan assay was found to be
0.05pg. No amplification was observed in other Mycobacterial spp. viz. M. phlei, M. smegmatis,
M. intracellulare and M. kansasii.

Background/Aims:
Gastric varices (GV) are present in 25% of cirrhotic patients with high rates of rebleeding and mortality. Data on endoscopic ultrasound (EUS)-guided treatment in severe liver disease (model for end stage liver disease sodium [MELD-Na] >18 and Child-Turcotte-Pugh [CTP] C with GV) are scarce. Thus, we performed a retrospective comparison of endoscopic glue injection with EUS-guided therapy in cirrhotic patients with large GV.
Methods:
A retrospective study was performed in the tertiary hospitals of India. A total of 80 patients were recruited. The inclusion criteria were gastroesophageal varices type 2, isolated gastric varices type 1, bleeding within 6 weeks, size of GV >10 mm, and a MELD-Na >18. Treatment outcomes and complications of endoscopic glue injection and EUS-guided GV therapy were compared.
Results:
In this study, the patients’ age, sex, liver disease severity (CTP, MELD-Na) and clinical parameters were comparable. The median number of procedures, injected glue volume, complications, and GV obturation were better in the EUS group, respectively. On subgroup analysis of the EUS method (e.g., direct gastric fundus vs. paragastric collateral [PGC] coil placement), PGC coil placement showed decreased coil requirement, less injected glue volume, decreased luminal coil extrusion, and increased successful GV obturation.
Conclusions
EUS-guided treatment is more efficient and safer, and requires a smaller number of treatment sessions, as compared to endoscopic treatment in severe liver disease patients with large GV. Furthermore, PGC coil placement increases the complete obliteration of GV.

Freeze-thaw cycles impact the amount of aggregation observed in antibodies and Fc-fusion proteins. Various formulation strategies are used to mitigate the amount of aggregation that occurs upon putting a protein solution through a freeze-thaw cycle. Additionally, low pH solutions cause native antibodies to unfold, which are prone to aggregate upon pH neutralization. There is great interest in the mechanism that causes therapeutic proteins to aggregate since aggregate species can cause unwanted im-munogenicity in patients. Herein, an increase in aggregation is reported when the pH is adjusted from pH 3 up to a pH ranging from pH 4 to pH 7 during the thaw process of a frozen antibody solution. Raising the pH during the thaw process caused a significant increase in the percent aggregation observed. Two antibodies and one Fc-fusion protein were evaluated during the pH jump thaw process and similar ef-fects were observed. The results provide a new tool to study the kinetics of therapeutic protein ag-gregation upon pH increase.

A simple, rapid and sensitive ultra performance liquid chromatography-tandem mass cilostazol and its pharmacologically active metabolite 3,4-dehydro cilostazol in human plasma using deuterated analogs as internal standards (ISs). Plasma samples were prepared using solid phase extraction 18 (50 mm ? 2.1 mm, 1.7 mm) column. The method was established over a concentration range of 0.5–1000 ng/mL for cilostazol and 0.5–mL for 3,4-dehydro cilostazol. Intra-and inter-batch precision (%CV) and accuracy for the analytes were found within 0.93–1.88 and 98.8–101.7% for cilostazol and 0.91–2.79 and 98.0–102.7% for the metabolite respectively. The assay recovery was within 95–97% for both the analytes and internal standards. The method was successfully applied to support a bioequivalence study of 100 mg cilostazol in 30 healthy subjects.

COVID-19, a highly contagious and deadly virus rapidly swept across the world from the year 2019 to 2020 killing more than two million people. Due to the magnitude of affect the virus was having, governments were forced into taking measures that required isolation of the infected from the unaffected, as mitigation to halt the spread. This brought about the “COVID-19 Lockdown”. Though the Pacific Island Countries (PICs) were with one of the least numbers of COVID-19 cases, similar measures were implemented as measure to prevent the virus from entering the countries. Like other countries, PICs like Fiji had a lockdown and this affected the lifestyles of the people. Amidst the lockdown, there was a rise in domestic violence cases. The literature review was done using databases; Medline, ProQuest, Embase, and Scopus. The research was done by using the relevant keywords in the field of COVID-19 which was aimed specifically on domestic violence during the pandemic. Moreover, local, and international publications, like media reports and published reports were also used. Upon carrying out this research it could be stated that there was a rise in the number of domestic violence cases in the wake of the COVID-19 pandemic lockdown. The literature review was aimed at identifying the consequences of COVID-19 and why it triggered a spike in domestic violence cases. The study concluded that the psychological impacts, and socio-economic state created as the result of the lockdown was the main contributing factor which gives rise to substance abuse, depression, which collectively lead to violence

A pig was confirmed to be a true hermaphrodite on the basis of gross and histomorphological studies of the genital organs. The genitalia was consisted of left ovary, oviduct, two coiled uterine horns, body of uterus alongwith right testis and an epididymis. Vagina and vulva were absent but male urethra with prostate gland was present. Grossly the size of all the genital organs appeared to be normal. Histomorphologically, testis and epididymis were underdeveloped as there was no clearcut spermatogenia and sertoli cells but Leydig cells were normal. The ovary presents normal histological features with some portion of testicular tissue. Degeneration of uterine epithelium was observed along with normal endometrial glands.

OBJECTIVE: As the literature for the treatment of functional (psychogenic) movement disorders (FMD) is sparse, we assessed clinical outcomes in patients with FMD who underwent treatment with psychodynamic psychotherapy (PDP). METHODS: A retrospective analysis of the data of patients with FMD who were referred for PDP from 2008−2014 at Emory University Medical Center was performed. RESULTS: Thirty patients were included, mean age at presentation was 50 years (SD 13.9) and majority were female (27/30). Most common movement disorder was involuntary shaking/jerky movements (50%) and tremor (43%). Mean duration of symptoms was 3.2 years and mean number of PDP visits was 4.9. PDP lead to good outcomes in 10, modest in 8, and poor in 9. Three patients lost to follow up. Mean duration of symptoms between two groups (good vs. poor) was not statistically significant (p = 0.11), mean number of PDP visits showed a trend towards significance (p = 0.053). In all cases of good outcomes precipitants of the movement disorder were identified and a majority (60%) was receptive of the diagnosis and had good insight. CONCLUSION: PDP lead to improvement in 60% of the patients which is encouraging as the treatment is challenging. This study supports heterogeneous causes of FMD including varied roles of past/recent events and demonstrates importance of psychological approaches such as PDP. Treatment with PDP should be considered in some patients with FMD but predicting who will respond remains a challenge. Further long term prospective studies with large sample size and placebo control are needed.

Diabetes mellitus has become one of the most common chronic diseases, thereby posing a major challenge to global health. Characterized by high levels of blood glucose (hyperglycemia), diabetes usually results from a loss of insulin-producing β-cells in the pancreas, leading to a deficiency of insulin (type 1 diabetes), or loss of insulin sensitivity (type 2 diabetes). Both types of diabetes have serious secondary complications, such as microvascular abnormalities, cardiovascular dysfunction, and kidney failure. Various complex factors, such as genetic and environmental factors, are associated with the pathophysiology of diabetes. Over the past two decades, the role of small, single-stranded noncoding microRNAs in various metabolic disorders, especially diabetes mellitus and its complications, has gained widespread attention in the scientific community. Discovered first as an endogenous regulator of development in the nematode Caenorhabditis elegans, these small RNAs post-transcriptionally suppress mRNA target expression. In this review, we discuss the potential roles of different microRNAs in diabetes and diabetes-related complications.
