Continuous flow solvent-free and catalyst-free mechanochemical production of rhodamine B dyes and their derivatives.

In this communication, we have described a simple and efficient, catalyst free and solvent-free protocol for the continuous flow synthesis of rhodamine B dyes developed from 3-diethyl amino phenol and phthalic anhydride. Nearly 95% conversion was achieved within 12 min using a jacketed single screw reactor. This method is further used for the synthesis of six derivatives with 70-84% yield, which can be compared to 85% yield from a 1-hour long batch synthesis involving a catalyst.

Factors associated with the delay in diagnosis of extrapulmonary tuberculosis at the patient and health system level: A study from a rural setting in India.

Background: With the proportion of tuberculosis cases that are extrapulmonary tuberculosis (EPTB) increasing in recent years, understanding and addressing factors contributing to the prolonged time to diagnosis (TTD) of EPTB patients is vital.

Methods: We enrolled presumptive EPTB patients for a cohort study from 2018-2020 in Ujjain, India. Based on a structured questionnaire, the patients were interviewed for socio-demographic and clinical information, including previously visited health facilities (HF) for this illness.

Health-related quality of life among extrapulmonary tuberculosis patients and inequalities by disease manifestations: a longitudinal study analysing the impact of TB treatment.

Background: To understand the impact of extrapulmonary tuberculosis (EPTB) and its treatment on quality of life, we analysed patient-reported outcome measures (PROMs) among presumptive ETPB patients.

Methods: EuroQol's five-dimensional three-level (EQ-5D-3L) questionnaire and the Visual Analogue Scale (EQ-VAS) were used to measure PROMs by 274 presumptive EPTB patients at pre- and post-treatment stages. The patients were categorised as TB and non-TB by using a composite reference standard.

Management of jump space in immediate implants with and without demineralised freeze dried bone allograft: a randomised controlled trial.

Purpose: The present study aimed to evaluate and compare the management of Jump space (JS) in immediate implants with and without Demineralised freeze-dried bone allograft (DFDBA) with flapless approach.

Materials And Methods: The present study included 40 sites with immediate implant placement in the maxillary anterior region. Group 1 patients were treated without augmentation while Group 2 patients with DFDBA in the JS.

Milk derived extracellular vesicle uptake in human microglia regulates the DNA methylation machinery : Short title: milk-derived extracellular vesicles and the epigenetic machinery.

Mammalian milk contains milk-derived extracellular vesicles (MEVs), a group of biological nanovesicles that transport macromolecules. Their ability to cross the blood brain barrier and the presence of cargo capable of modifying gene function have led to the hypothesis that MEVs may play a role in brain function and development. Here, we investigated the uptake of MEVs by human microglia cells in vitro and explored the functional outcomes of MEV uptake.
