New drugs are needed to combat multidrug-resistant tuberculosis. The electron transport chain (ETC) maintains the electrochemical potential across the cytoplasmic membrane and allows the production of ATP, the energy currency of any living cell. The mycobacterial engine F-ATP synthase catalyzes the formation of ATP and has come into focus as an attractive and rich drug target. Recent deep insights into these mycobacterial FF-ATP synthase elements opened the door for a renaissance of structure-based target identification and inhibitor design. In this study, we present the GaMF1.39 antimycobacterial compound, targeting the rotary subunit γ of the biological engine. The compound is bactericidal, inhibits infection , and displays enhanced anti-tuberculosis activity in combination with ETC inhibitors, which promises new strategies to shorten tuberculosis chemotherapy.

Background: Brucellosis remains a significant public health and economic challenge in Egypt despite long-standing control efforts. This paper outlines the national strategy for brucellosis control, detailing its legal framework, diagnostic protocols, surveillance mechanisms, vaccination programs, and biosecurity measures.
Main Body: Egypt employs a dual approach of test-and-slaughter and selective vaccination, supported by serological and pathological diagnostics.

Background: PPM1D (protein phosphatase Mg⁺/Mn⁺ dependent 1D) is a Ser/Thr phosphatase that negatively regulates p53 and functions as an oncogenic driver. Its gene amplification and overexpression are frequently observed in various malignancies and disruption of PPM1D degradation has also been reported as a cause of cancer progression. However, the precise mechanisms regulating PPM1D stability remain to be elucidated.

Objective: Progesterone (PG) and its target, progesterone receptor (PGR), are important regulators in inflammatory diseases. This study aimed to investigate the specific role of PG in periodontitis and to elucidate the underlying mechanisms involving PGR.
Methods: Women with periodontitis, including 250 with PG deficiency, 250 with PG supplementation, and 245 controls (normal PG) were enrolled.

Itaconate is an immunomodulatory metabolite that alters mitochondrial metabolism and immune cell function. This organic acid is endogenously synthesized by tricarboxylic acid (TCA) metabolism downstream of TLR signalling. Itaconate-based treatment strategies are under investigation to mitigate numerous inflammatory conditions.
