INTRODUCTION: Lipoma is the most familiar soft-tissue tumor. But the etiology of lipoma remains imprecise. Sex steroid hormones such as estrogen have effects on muscle and adipose tissue development. There is now significant evidence that sex steroids are involved in the site specificities of adipose tissue metabolism. This association of adipose tissue metabolism between sex steroid hormones suggests a possible role for sex steroids in the pathogenesis of lipoma. METHODS: To investigate this concept, the authors evaluated the expression of the estrogen receptor (ER) and the progesterone receptor (PR) in soft tissue lipoma in this study...

In the pathogenesis of neonatal intraventricular hemorrhage (IVH) in preterm infants, an important role is played by changes in venous and arterial cerebral flows. It has been shown that the ability of autoregulation of cerebral flows in response to variations in arterial blood pressure in preterm infants is impaired. This impaired autoregulation causes an increased risk of germinal matrix rupture and IVH occurrence. We examined three polymorphisms of genes, related to regulation of blood flow, for an association with IVH in 100 preterm infants born from singleton pregnancy, before 32 + 0 weeks of gestation, exposed to antenatal steroids therapy, and without congenital abnormalities...

In search of antiparasitic agents, we here identify arylmethylamino steroids as potent compounds and characterize more than 60 derivatives. The lead compound 1o is fast acting and highly active against intraerythrocytic stages of chloroquine-sensitive and resistant Plasmodium falciparum parasites (IC50 1-5 nM) as well as against gametocytes. In P. berghei-infected mice, oral administration of 1o drastically reduces parasitaemia and cures the animals. Furthermore, 1o efficiently blocks parasite transmission from mice to mosquitoes...

An important development in the field of macrocyclization strategies towards molecular cages is described. The approach comprises the utilization of a double Ugi four-component macrocyclization for the assembly of macromulticycles with up to four different tethers, that is, hybrid cages. The innovation of this method rests on setting up the macromulticycle connectivities not through the tethers but through the bridgeheads, which in this case involve N-substituted amino acids. Both dilution and metal-template-driven macrocyclization conditions were implemented with success, enabling the one-pot formation of cryptands and cages including steroidal, polyether, heterocyclic, peptidic, and aryl tethers...

Pemphigus is an autoimmune B-cell mediated blistering disease associated with significant morbidity and mortality. Rituximab has proven effective for the treatment of steroid-refractory pemphigus, although there is controversy over the optimum dosing protocol. Additionally, effective disease control often requires long-term immunosuppression, even in disease-free periods. We present a case series of a single-centre long-term follow up of nine patients with pemphigus, treated with two 500-mg doses of rituximab separated by 14 days along with concurrent adjuvant therapy...

BACKGROUND: Complement factor B gene (CFB) is an important component of the alternate pathway of complement activation that provides an active subunit that associates with C3b to form the C3 convertase, which is an essential element in complement activation. Among the complement-associated disorders, mutations and pathogenic variants in the CFB gene are relatively rare phenomena. Moreover, mutated CFB affiliation with immune-complex diffuse membranoproliferative glomerulonephritis (IC-MPGN) and atypical hemolytic uremic syndrome (aHUS) are considered a highly rare occurrence...

INTRODUCTION: Sensory blockade of the brachial plexus with local anaesthetics for perioperative analgesia leads to stable haemodynamics intraoperatively, smoother emergence from general anaesthesia and decreased need for supplemental analgesics or suppositories in the Post-operative period. However, increasing the duration of local anaesthetic action is often desirable because it prolongs surgical anaesthesia and analgesia. Various studies in adults prove that steroids increase the duration of action of local anaesthetics when used as adjuncts...

Glutamate dehydrogenase (GDH) is a hexameric enzyme that catalyzes the reversible conversion of glutamate to α-ketoglutarate and ammonia while reducing NAD(P)⁺ to NAD(P)H. It is found in all living organisms serving both catabolic and anabolic reactions. In mammalian tissues, oxidative deamination of glutamate via GDH generates α-ketoglutarate, which is metabolized by the Krebs cycle, leading to the synthesis of ATP. In addition, the GDH pathway is linked to diverse cellular processes, including ammonia metabolism, acid-base equilibrium, redox homeostasis (via formation of fumarate), lipid biosynthesis (via oxidative generation of citrate), and lactate production...
