Calcium (Ca) is a universal signaling cation with a prominent role as second messenger in many different plant processes, including sexual reproduction. However, there is much less knowledge about the involvement of Ca during embryogenesis processes. In this work we performed a study of Ca levels during the different stages of microspore embryogenesis in , with special attention to how Ca can influence the occurrence of different embryogenic structures with different embryogenic potential.

Outcomes of theoretical models on conflict resolution between investing partners in bi-parental care systems typically predict "partial compensation" or "matched" response rules, depending on underlying assumptions. Further, although experimental tests in birds suggest that care levels by pair members are largely associated with partial compensation responses, this outcome partly depends on the type of experiment used and its effects on model assumptions. To elucidate support for both the underlying assumptions and predictions of models predicting partner compensation versus matching, we performed temporary, bi-directional brood size manipulations during late nestling provisioning in blue tits () in the French Pyrenees.

Department of Microbiology, All India Institute of Medical Sciences, New Delhi, India.
Background And Objectives: Anorectal and pharyngeal infections with (NG) are common in men who have sex with men (MSM). However, they are often asymptomatic and found in the absence of reported risk behavior and concurrent genital infection. These serve as a hidden reservoir for ongoing transmission and may cause complications.

BMJ Oncol
August 2024
Division of Uro Oncology, ACTREC, Tata Memorial Centre, Homi Bhabha National Institute, Mumbai, Maharashtra, India.
Objective: To compare health-related quality of life (HRQOL) in patients undergoing radical cystectomy with ileal conduit (RC) or bladder preservation (BP) with (chemo)radiotherapy for bladder cancer.
Methods And Analysis: Patients with bladder cancer, stage cT1-T4, cN0-N1, M0 with a minimum follow-up of 6 months from curative treatment (RC or BP) and without disease were eligible for inclusion. Two HRQOL instruments were administered: Bladder Cancer Index (BCI) for bladder cancer-specific HRQOL and European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30).
Understanding and Deterring Online Child Grooming: A Qualitative Study.
Sex Offending
February 2024
The Lucy Faithfull Foundation, Epsom, United Kingdom.
The prevalence of online child sexual grooming offenses has been on the rise, posing significant risks to children. Child sexual grooming involves sexual communication with minors. This study aims to understand motivations and pathways of individuals who have engaged in online grooming behaviour, as well as propose effective prevention and intervention strategies.
