Two independent twin-arginine translocases (Tat) for protein secretion were previously identified in the Gram-positive bacterium Bacillus subtilis. These consist of the TatAd-TatCd and TatAy-TatCy subunits. The function of a third TatA subunit named TatAc was unknown. Here, we show that TatAc can form active protein translocases with TatCd and TatCy.

The breaking of inversion symmetry combined with spin-orbit coupling, can give rise to intrigu- ing quantum phases and collective excitations. Here, we report systematic temperature dependent Raman scattering and theoretical calculations of phonon modes across the inversion symmetry- breaking structural transitions in a quasi-one-dimensional compound (TaSe4)3I. Our investigation revealed the emergence of three additional Raman-active modes in Raman spectra of the low- temperature (LT) non-centrosymmetric (NC) structure of the material.

Background And Aims: For the aggressive treatment of postoperative pain, nonpharmacological methods (NPMs) are gaining importance complementary to routine multimodal pain management. The primary aim of the study was to assess the incidence of use of NPMs in our hospital. Secondary objectives were to correlate the pain scores, patient satisfaction, and percentage of time the patient was in severe pain within 72 h postsurgery with the use of NPMs when in pain/not in pain.

Aim: To evaluate the efficacy of 25Gy/5# prophylactic pelvic nodal irradiation for regional control during stereotactic radiotherapy (SBRT) for high risk prostate cancer.
Methods: The multinational XXXX consortium database of patients treated with curative-intent prostate SBRT for high risk prostate cancer was queried for prophylactic radiotherapy 25Gy/5# to the pelvic lymph nodes. Details of Phoenix-defined biochemical failure, and location of recurrence (local, regional, or distant) were extracted.
Designing a summative assessment blueprint in community medicine: an expert consensus approach at All India Institute of Medical Sciences.

Department of Community and Family Medicine, All India Institute of Medical Sciences, Patna, India.
Background: Despite the increasing integration of competency-based education in medicine, there remains a significant gap in effectively assessing educational outcomes, underscoring the urgent need for designed assessment blueprints that accurately reflect both curriculum content and competency standards in Community Medicine for undergraduate students. This study, conducted across the All-India Institute of Medical Sciences (AIIMS) network, develops a summative assessment blueprint aimed at standardizing evaluations in medical education across diverse geographic locations in India.
Methods: Twenty-five experts from 10 All India Institutes of Medical Science were invited via email and contributed for summative assessment for a theory paper.
