Lower gastrointestinal bleeding is a rare condition in childhood pathology. The incidence of this disorder in the general population of Bulgarian children is unknown. We report a case of a 7-year-old child with diagnosed hemophilia A and high titer of factor VIII inhibitor; the patient was admitted into the Department of Pediatrics and Medical Genetics for rectorrhagia after falling onto his buttocks while playing. Colonoscopy showed submucosal hematoma 25 cm from the anocutaneous line occluding the intestinal lumen with a lesion of the overlying mucosa as long as 20 mm. If a patient presents with rectorrhagia, timely and carefully planned colonoscopy could identify the source of bleeding, determine the severity of bleeding and the size of hematoma, and assess the need for surgical intervention. The reported case supports the modern view that patients with inhibitor hemophilia should not be denied interventional procedure or surgical intervention for fear of uncontrolled bleeding.

Typical renal involvement of antineutrophilic cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is pauci-immune glomerulonephritis that presents clinically as rapidly progressive renal failure (RPRF). Here, we report an unusual presentation of myeloperoxidase (MPO)-specific ANCA with isolated involvement of the tubulointerstitium in the form of peritubular capillaritis as the sole lesion without any involvement of the glomerulus. A 52-year-old woman with no previous comorbidities presented with nonspecific symptoms such as fatigue, dysuria, and nausea for two months.

New Onset Refractory Status Epilepticus (NORSE) is a rare and severe condition characterized by refractory seizures in individuals without a prior history of epilepsy. This case report describes a 37-year-old woman diagnosed with anti-glutamic acid decarboxylase 65 (anti-GAD65) antibody-positive encephalitis-related NORSE. Her seizures were refractory to multiple interventions, including anti-seizure medications, anesthetics, immunotherapies, a ketogenic diet, and electroconvulsive therapy.

Objective The prevalence of drug-resistant Mycobacterium tuberculosis (Mtb) strains is exacerbating the global burden of tuberculosis (TB), highlighting the urgent need for new treatment strategies for TB. Methods The recombinant adenovirus vaccine expressing cyclic di-adenosine monophosphate (c-di-AMP) phosphodiesterase B (CnpB) (rAd-CnpB), was administered to normal mice via mucosal immunization, either alone or in combination with drug therapy, to treat Mtb respiratory infections in mice.Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of antibodies in serum and bronchoalveolar lavage fluid (BALF).

Background: The industrial production of L-threonine faces challenges because of high production costs, especially those of substrates, meaning new production methods are needed.
Methods: Fur, a new global transcription factor related to L-threonine biosynthesis, was discovered in this study. Multidimensional regulation combined with global transcriptional machinery engineering was used to modify an Escherichia coli strain.

Due to the lack of specific antibody anti-chicken tumor necrosis factor receptor-associated factor 2 (TRAF2), it is difficult to further explore the role of TRAF2 in pulmonary artery remodeling in pulmonary hypertension(PH) in broilers. In this experiment, we prepared a polyclonal antibody to TRAF2 by constructing a TRAF2 recombinant protein prokaryotic expression vector and analyzed the expression of TRAF2 in in vivo and in vitro models of pulmonary hypertension in broiler chickens and the effect of TRAF2 on the activity and apoptosis of PASMCs. The results showed that after immunization with TRAF2 recombinant protein we obtained high titers of polyclonal antibodies, and astragalus polysaccharide as an immune adjuvant could enhance the effect of immunization.
