Clustered regularly interspaced short palindromic repeats-Cas system: diversity and regulation in Enterobacteriaceae.

Insights into the arms race between bacteria and invading mobile genetic elements have revealed the intricacies of the clustered regularly interspaced short palindromic repeats (CRISPR)-Cas system and the counter-defenses of bacteriophages. Incredible spacer diversity but significant spacer conservation among species/subspecies dictates the specificity of the CRISPR-Cas system. Researchers have exploited this feature to type/subtype the bacterial strains, devise targeted antimicrobials and regulate gene expression.

Microbiological profile of canaliculitis and their antibiotic susceptibility patterns: A 11-year review at a referral eye care centre.

Purpose: To analyze the microbiological profile and in vitro antibiotic susceptibility patterns of bacterial isolates in canaliculitis, an infection of the lacrimal drainage system of the eye.

Methods: The laboratory records of patients presenting with canaliculitis from whom specimens were obtained for microbiological investigations at our tertiary eye care centre in South India from January 2010 to December 2020, were reviewed.

Results: A total of 130 canalicular pus samples were collected from 112 patients and submitted for microbiological studies during the study period.

Improving Fracture Toughness of Tetrafunctional Epoxy with Functionalized 2D Molybdenum Disulfide Nanosheets.

In this work, improved fracture toughness of tetra-functional epoxy polymer was obtained using two-dimensional (2H polytype) molybdenum disulfide (MoS) nano-platelets as a filler. Simultaneous in-situ exfoliation and functionalization of MoS were achieved in the presence of cetyltrimethylammonium bromide (CTAB) via sonication. The aim was to improve the dispersion of MoS nanoplatelets in epoxy and enhance the interfacial interaction between nanoplatelets and epoxy matrix.

Factors associated with homelessness among women: a cross-sectional survey of outpatient mental health service users at The Banyan, India.

Background: Homelessness has multifaceted and damaging effects on women with mental illness. This makes it imperative to identify and address the factors leading to homelessness among women with mental illness in order to inform policy on providing relevant services for this vulnerable population.

Method: A cross-sectional survey was conducted among 346 women in active contact with one of four outpatient clinics at The Banyan, a non-profit organization in the Indian state of Tamil Nadu.

Prevalence, service use and clinical correlates of hallucinations and delusions in an out-patient population from India.

Background: Despite the persistent public health problem of positive psychotic symptoms, understanding of symptom specific prevalence rates, clinical correlates and service utilisation are sparse.

Aims: The current study aimed to establish prevalence, clinical and service utilisation correlates of hallucinations and delusions in people accessing outpatient clinics in Tamil Nadu, India.

Methods: Secondary patient data from outpatient clinics, over a 12-month period, in 2016, was used for analysis ( = 917).
