Monitoring biodiversity on a large scale, such as in hydropower reservoirs, poses scientific challenges. Conventional methods such as passive fishing gear are prone to various biases, while the utilization of environmental DNA (eDNA) metabarcoding has been restricted. Most eDNA studies have primarily focused on replicating results from traditional methods, which themselves have limitations regarding representativeness and bias.

Background: Accurate scientific terminology is crucial in health sciences to avoid misinterpretations. The use of 'artemisinin resistance' to describe delayed parasite clearance may be inaccurately equated with full resistance, as is typically the case when 'resistance' is used with other pathogens, leading to potential confusion. In 2018, the World Health Organization (WHO) introduced 'partial artemisinin resistance' to more accurately reflect the delayed parasite clearance observed with artemisinin-based therapies.

Article Synopsis
  • - Fetal autoimmune atrioventricular block (AVB) is a rare condition caused by maternal anti-SSA/Ro or Anti-SSB/La auto-antibodies affecting the fetal heart, leading to serious issues like inflammation and damage to the AV node.
  • - A patient with a history of high antibody levels and hypothyroidism showed improvements in a first-degree AV block during pregnancy after treatment with dexamethasone and intravenous immunoglobulin.
  • - The fetus later developed a tachyarrhythmia requiring medication, and after birth, was diagnosed with Wolff-Parkinson-White Syndrome (WPWS), marking the first known instance of AVB co-existing with WPWS.

Article Synopsis
  • - Asthma is a common chronic respiratory condition marked by hyper-responsiveness of the airways and occasional obstruction, with short-acting β agonists (SABA) being the main treatment for acute episodes.
  • - A case is reported where a young female patient experienced lactic acidosis after being treated with SABA, specifically salbutamol, for severe acute asthma; this was linked to her treatment despite showing significant improvement in breathing.
  • - After stopping the SABA treatment, the patient's symptoms, including respiratory distress and elevated lactate levels, improved quickly, and she was discharged after five days; this incident highlights the rare but important side effect of lactic acidosis associated with SABA use.

Nitrite is a nitric oxide (NO) metabolite, which may be bioactivated to generate NO in vivo and supplement endogenous NO formation, especially in cardiovascular and metabolic diseases. However, it is not known whether treatment with oral nitrite results in the accumulation of NO metabolites in different organs. Moreover, treatment with omeprazole, an inhibitor of gastric acid secretion, severely affects the gastric formation of S-nitrosothiols induced with oral nitrite treatment.

The increasing global pressure to explore alternative protein sources derived from animal by-products has opened-up opportunities, but it has also created the need to assess their compliance with labelling statements, to ensure consumer's trust in the composition of both feed and food products. Assessing the authenticity of highly processed animal by-products, particularly within the rapidly expanding Halal food market, presents a significant challenge due to the lack of robust and standardized methodologies. However, the success of DNA based authenticity system is highly dependent on the extracted DNA quantity, quality, and purity ratios from heterogeneous matrices.

Oral diseases affect over three billion people worldwide, making it one of the most common infections. Recent studies show that one approach to reducing the risk of chronic infections, such as caries, gingivitis, periodontitis, and halitosis, is to control the ecology of the oral microbiome instead of completely removing both the harmful and beneficial microorganisms. This is based on the knowledge that oral diseases are not caused by a single pathogen but rather by a shift in the homeostasis of the entire microbiota, a process known as dysbiosis.

The anterior cingulate cortex (ACC) Cg1 (24b) area modulates glutamate-mediated unconditioned fear and antinociception organised by hypothalamus. However, it remains unknown whether 24b area also modulates these latter defensive responses through connections with the dorsal periaqueductal grey matter (dPAG), a midbrain structure implicated in the genesis of innate fear-induced defence. The aim of this work is to examine the correlation between the behavioural effects of intra-ACC microinjections of vehicle, NMDA (1 nmol) or lidocaine (2%) with Fos protein expression and nitrergic activity in the dPAG of male C57BL/6 mice that were threatened by snakes.

Neuropsychiatric symptoms and syndromes are among the most common non-motor symptoms of Parkinson's Disease but they are frequently unrecognized and untreated. Dopamine Dysregulation Syndrome is an uncommon complication of the treatment of Parkinson's disease, characterized by an addictive use of dopamine far more than the dosage required for treatment of objective motor impairment, leading to severe dyskinesia, euphoria, aggressivity, or psychosis. We present a paradigmatic case of Dopamine Dysregulation Syndrome, Mania, and Compulsive Buying in a 55-year-old male with Parkinson's Disease.
