One-third of the world's population is infected with Mycobacterium tuberculosis (M.tb.). Latent tuberculosis infection (LTBI) can progress to tuberculosis disease, the leading cause of death by infection. Rifamycin antibiotics, like rifampin and rifapentine, have unique sterilizing activity against M.tb. What are the advantages of each for LTBI or tuberculosis treatment? Areas covered: We review studies assessing the pharmacokinetics (PK), pharmacodynamics (PD), drug interaction risk, safety, and efficacy of rifampin and rifapentine and provide basis for comparing them...

We present a rare case of a large infarcted submucous fibroid removed manually after a normal vaginal delivery. This patient was known to have a large postero-fundal hybrid predominantly intramural uterine fibroid, measuring 11 x 10 cm in diameter and diagnosed 2 years prior to last conception. Thirty-five days postpartum, she presented with severe lower abdominal pain and foul smell per vaginum. Abdominal examination revealed a very tender bulky uterus at 24 weeks size, and vaginal examination revealed a big fleshy smelly mass with friable surface just bulging from a dilated cervix...

Effects of ribavirin on the structure of peritubular sheath (PS) of seminiferous tubules and on testicular functions were studied. We found that ribavirin at a dose of 4 mg/kg/day for 4 weeks produced a significant reduction in testosterone level (6.3 ± 0.2; P < 0.001) and in spermatogenic score count (3.8 ± 0.2; P < 0.001) compared to control values. The thickness of PS (17.8 ± 1.13) and tubular lumen perimeter (1024.7 ± 67) was significantly increased compared to controls (10...

DNA encoding the coat protein (CP) of an Egyptian isolate of tomato yellow leaf curl virus (TYLCV) was inserted into the genome of Autographa californica nucleopolyhedrovirus (AcNPV) under the control of polyhedrin promoter. The generated recombinant baculovirus construct harboring the coat protein gene was characterized using PCR analysis. The recombinant coat protein expressed in infected insect cells was used as a coating antigen in an indirect Enzyme-linked immunosorbent assay (ELISA) and dot blot to test its utility for the detection of antibody generated against TYLCV virus particles...

Medical imaging modalities such as computed tomography (CT) combined with computer-aided diagnostic processing have already become important part of clinical routine specially for pleural diseases. The segmentation of the thoracic cavity represents an extremely important task in medical imaging for different reasons. Multiple features can be extracted by analyzing the thoracic cavity space and these features are signs of pleural diseases including the malignant pleural mesothelioma (MPM) which is the main focus of our research...

Pancreatic islet transplantation is a promising therapy for patients with type 1 diabetes. However, the duration of long-term graft survival is limited due to inflammatory as well as non-inflammatory processes and routine clinical tests are not suitable to monitor islet survival. (111)In-exendin-SPECT (single photon emission computed tomography) is a promising method to non-invasively image islets after transplantation and has the potential to help improve the clinical outcome. Whether (111)In-exendin-SPECT allows detecting small differences in beta-cell mass (BCM) and measuring the actual volume of islets that were successfully engrafted has yet to be demonstrated...

BACKGROUND: The prevalence of heart failure is increasing in Lebanon but to date there is no systematic evaluation of a disease management intervention. OBJECTIVE: The aim of this study was to evaluate the effect of involving family caregivers in the self-care of patients with heart failure on the risk of hospital readmission. DESIGN: A multi-site, block randomised controlled trial. SETTINGS: The study was conducted over a 13-month period in three tertiary medical centres in Beirut and Mount Lebanon, Lebanon...

The development of robust and efficient strategies to access structurally diverse drug-like compound collections remains an important challenge for small molecule probe development and drug discovery. Following a build/couple/pair strategy we have established bidirectional approach to unprecedented benzoxazepines by employing a Pictet-Spengler/aza-Michael addition cascade and Schiff base/aza-Michael addition/reduction protocols, respectively. The corresponding β-carboline-fused benzoxazepines and peripherally substituted benzoxazepines are isolated in high diastereoselectivity, good to excellent yields and have, to the best of our knowledge, never been reported...

INTRODUCTION: The outcomes of total hip arthroplasty (THA) for the treatment of posttraumatic arthritis after acetabular fractures were inferior to those after primary non-traumatic THA. METHODS: This study was performed in academic level I trauma center. From January 2011 to December 2014, a consecutive series of 21 patients (9 females), with average age of 56.7 years (range 29-75 years) who had posttraumatic hip joint arthritis after acetabular fractures, were included in our study...

Frequency-dependent plasticity (FDP) describes adaptation at the synapse in response to stimulation at different frequencies. Its consequence on the structure and function of cortical networks is unknown. We tested whether cortical "resonance," favorable stimulation frequencies at which the sensory cortices respond maximally, influenced the impact of FDP on perception, functional topography, and connectivity of the primary somatosensory cortex using psychophysics and functional imaging (fMRI). We costimulated two digits on the hand synchronously at, above, or below the resonance frequency of the somatosensory cortex, and tested subjects' accuracy and speed on tactile localization before and after costimulation...

Marek's disease (MD) is a lymphoproliferative disease causing a serious threat in poultry production. Field strains of Marek's disease virus (MDVs) are continuously re-emerging, causing great economical losses to the poultry industry worldwide in spite of the intensive vaccination and restrictive management policy used. Histopathological and molecular characterizations of MDVs are essential for monitoring the changes of viruses and evaluating the effectiveness of existing vaccines. During 2016, 190 visceral tumor tissues representing 30 vaccinated chicken flocks from Gifu prefecture, Japan were analyzed...

Idiopathic pneumonia syndrome (IPS) is a complication of allogeneic hematopoietic stem cell transplantation (HSCT) that typically occurs within the first 100 days after transplantation. Tumor necrosis alpha-α (TNF-α) has been shown to be a key mediator of IPS, and the TNF-α binding protein, etanercept, appears to improve IPS outcomes in small retrospective and prospective studies. IPS has also been observed to occur later (>100 days) after HSCT; however, little is known about the disease course and whether a TNF-α-based therapeutic strategy is efficacious in these patients...

Diabetic foot, one of the most common and debilitating manifestations of type 2 diabetes mellitus (T2DM), is the leading cause of worldwide non-traumatic lower extremity amputations. Diabetics who are at risk of ulceration are currently mainly identified by a thorough clinical examination of the feet, which typically does not show clear symptoms during the early stages of disease progression. In this study, we used a non-linear dynamics tool, gait entropy (GaitEN), in addition to traditional linear gait analysis methods, to investigate gait alterations amongst diabetic patients with combinations of three types of T2DM related complications: retinopathy, diabetic peripheral neuropathy (DPN) and nephropathy...
