Loeys-Dietz syndrome (LDS) is a rare, recently described, autosomal dominant, connective tissue disease characterized by aggressive arterial aneurysms, resulting from mutations in the transforming growth factor beta (TGFβ) receptor genes TGFBR1 and TGFBR2. Mean age at death is 26.1 years, most often due to aortic dissection. We report an unusually late presentation of LDS, diagnosed following elective surgery in a female with a long history of joint hypermobility. Methods: A 51-year-old Caucasian lady complained of chest pain and headache following a dural leak from spinal anaesthesia for an elective ankle arthroscopy. CT scan and echocardiography demonstrated a dilated aortic root and significant aortic regurgitation. MRA demonstrated aortic tortuosity, an infrarenal aortic aneurysm and aneurysms in the left renal and right internal mammary arteries. She underwent ao...

The productivity of tomato, as a drought-sensitive crop, is highly restricted by drought stress. The current study aimed at introducing the OsDERB2A gene into two tomato genotypes via Agrobacterium-mediated transformation system. Cotyledonary explants were pre-cultured for two days with Agrobacterium strain LBA4404 harboring pCAMBIA1301 with OsDREB2A driven by the constitutive promoter CaMV35S for transformation. Shoots were directly regenerated on MS medium containing 1 mg l-1 zeatin and 1 mg l-1 BAP, and in presence of 30 mg l-1 hygromycin as selective agent. Only eight weeks were needed to regenerate transgenic tomato using this protocol. An OD600 of 0.4 resulted in 64.3-76.9% transformation efficiency. Stable integration and expression of the OsDREB2A gene were confirmed in transgenic tomato using PCR and RT-PCR analyses, and drought tolerance o...

The number of mites was recorded before and after treatments Biomectin caused the highest reduction in mite population (96.72 %) followed by Surfactant as a pesticide adhesive and Biomectin plus Surfactant which were recorded 92.09 and 70.45 %, respectively. The effect of fertilizers showed that the highest reduction (47.49 %) was occurred under soil addition of compost. Paclobutrazol as a growth regulator achieved the highest reduction (96.95%) of T. urticae..

Ultrasound (US) guidance is usually helpful for accurate needle placement and improves the outcome. Aim of the Work: The aim of the work was to evaluate the efficacy of US-guided injections compared to clinically guided injections, the treatment of flexor tenosynovitis in diabetic hands. Patients and Methods: Patients were divided into two matched groups of diabetic patients with flexor tenosynovitis: Group 1 – treated with local CS injection under US guidance and Group 2: treated with local CS injection under clinical guidance. Both the groups were assessed twice for pain and tenderness using visual analog scale (VAS) and Richie index, respectively, one before the injection and the second 1 month after. All affected tendons were assessed and graded by US and power Doppler at baseline and 1 month after the in...

The success of those vaccines depends mainly on immunologic memory. People who are at high risk of re-infection with COVID-19 don’t show any evidence of having B-cell memory. 10-20% of infected patients don’t develop antibody response. randomized controlled trials and cross-sectional studies proved variant results about the effect of chronic exercise on vaccination function.The aim of this review is to suggest that exercise is an important adjuvant strategy for prevention of re-infection and for development of better protective responses following vaccination.Methods: Embase, Medline and the Cochrane Central Register were used to search for specific keywords such as “COVID-19” OR “SARS-CoV-2” AND “Re-infection” for relevant publications up to 1st of Nov....

Survey revealed that, the existence of one species of mites, Tetranychus urticae Koch and four species of insects. Population densities and seasonal fluctuations in relation to weather conditions were estimated.
