The Indian coast has been experiencing an increase in algal bloom events over the decades. Owing to the regional and seasonal dynamics of algal biomass (proxy: chlorophyll-a, hereafter chl-a), a multitude of thresholds of chl-a has been defined for different parts of the global seas to determine algal bloom conditions. However, no such clear definition is given for the Indian coastal waters.

In heart failure, sympathetic overdrive is evidenced by norepinephrine spillover, receptor level changes, etc. Beta-blockers continue to be the cornerstone of treatment in patients with chronic heart failure due to their ability to counteract sympathetic overdrive. Extensive clinical research has demonstrated that long-term beta-blocker treatment with metoprolol succinate, carvedilol, or bisoprolol enhances left ventricular function and reverses left ventricular remodeling, decreases hospitalization risk, and increases survival.

Although parental sensitivity is an established determinant of children's attachment security, effect sizes are modest, suggesting other aspects of parenting that might support secure attachment. Parental emotion socialization (ES) has been proposed as a parenting domain that is theoretically linked to secure parent-child attachment. The goal of this meta-analysis was to evaluate the strength of the relations between parental ES and attachment security in children under the age of 18.

Article Synopsis
  • * Current guidelines recommend early combination therapy using four drug classes, especially ARNI, which significantly reduces morbidity and mortality in patients with heart failure with reduced ejection fraction (HFrEF).
  • * A national consensus by Indian cardiology experts emphasizes that ARNI should be initiated early in HFrEF patients, including those hospitalized, and can also benefit patients with preserved and mildly reduced ejection fractions.

Article Synopsis
  • Organisms, like C. elegans, activate their innate immune system to defend against pathogens, such as Pseudomonas aeruginosa, by using protective factors like SKN-1/NRF2.
  • Interestingly, C. elegans with constant SKN-1 activation exhibit an apathy-like behavior, choosing to stay and feed on the pathogen instead of avoiding it, despite better food options being available.
  • This apathy is linked to defects in serotonin signaling caused by SKN-1 activation, which ultimately reduces the worms' ability to defend against the pathogen and leads to adverse health effects.

Article Synopsis
  • The transcription factor SKN-1 is essential for several biological processes, including development, immune responses, and lifespan regulation in the organism.
  • This study focuses on the SKN-1 c isoform, investigating its specific role in development through the creation of mutants with targeted mutations in SKN-1 isoforms.
  • Findings indicate that SKN-1 c is critical for embryonic development, as mutants lacking it resulted in inviable embryos, whereas those with other SKN-1 isoforms developed normally.

The capacity to deal with stress declines during the aging process, and preservation of cellular stress responses is critical to healthy aging. The unfolded protein response of the endoplasmic reticulum (UPR) is one such conserved mechanism, which is critical for the maintenance of several major functions of the ER during stress, including protein folding and lipid metabolism. Hyperactivation of the UPR by overexpression of the major transcription factor, , solely in neurons drives lifespan extension as neurons send a neurotransmitter-based signal to other tissue to activate UPR in a non-autonomous fashion.

Article Synopsis
  • - In India, heart failure (HF) is a significant health issue, impacting younger individuals compared to Western countries, but many patients do not receive proper medical treatment.
  • - Selective β-1 blockers, like bisoprolol, are important in treating HF because they help lower heart rate and reverse negative heart and blood vessel changes associated with the condition.
  • - Despite the benefits of bisoprolol for various HF cases and comorbid conditions, its use in India remains suboptimal, prompting a consensus on its effectiveness and recommending it for better patient care.

Warfarin has been the most extensively used oral anticoagulant (OAC) in medical settings for over 60 years. Its uses, potential adverse effects, and methods for reversing its effects have been firmly established, rendering it a routine medication in medical settings where most professionals feel at ease employing it. Compared to other vitamin K antagonists (VKAs), such as acenocoumarol, warfarin offers benefits like diminished prothrombin time (PT) assays leading to enhanced oral anticoagulation.

Unlabelled: When an organism encounters a pathogen, the host innate immune system activates to defend against pathogen colonization and toxic xenobiotics produced. employ multiple defense systems to ensure survival when exposed to including activation of the cytoprotective transcription factor SKN-1/NRF2. Although wildtype quickly learn to avoid pathogens, here we describe a peculiar apathy-like behavior towards PA14 in animals with constitutive activation of SKN-1, whereby animals choose not to leave and continue to feed on the pathogen even when a non-pathogenic and healthspan-promoting food option is available.

Although theory suggests that empathy may signal a risk for anxiety (Tone & Tully, 2014), the relation between these constructs remains unclear due to the lack of a quantitative synthesis of empirical findings. We addressed this question by conducting three meta-analyses assessing anxiety and general, cognitive, and affective empathy (k's = 70-102 samples; N's = 19,410-25,102 participants). Results suggest that anxiety has a small and significant association with general empathy (r = .
