33% similarity) within the family Atopobiaceae. Cells were Gram-strain-positive and obligately anaerobic bacilli in chains. The optimum temperature and pH for the growth of the microorganism were 37-45 oC and pH 6.0-7.5 respectively. This strain produced acetic acid as the primary fermentation product. Major fatty acids were C 120, C 140, C 140 DMA and summed feature 1 (C 131 at 12-13 and C 140 aldehyde). Strain SW165 T exhibited a genome size of 2.43 Mbp with a G+C content of 67.59 mol%, which is the second highest G+C content among members of the genus Olsenella. The digital DNA-DNA hybridization and OrthoANI values between SW165 T and DSM 13989 T were only 17.6 ± 5.3 and 74.35%, respectively. Conclusion Based on the phenotypic, biochemical, and genomic analyses, we propose the new species of the genus Olsenella, and name it Olsenella lakotia SW165 T sp. nov., (=DSM 107283 =CCOS 1887) as the type strain.Virtually all aspects of T and B lymphocyte development, homeostasis, activation, and effector function are impacted by the interaction of their clonally distributed antigen receptors with antigens encountered in their respective environments. Antigen receptors mediate their effects by modulating intracellular signaling pathways that ultimately impinge on the cytoskeleton, bioenergetic pathways, transcription, and translation. Although these signaling pathways are rather well described at this point, especially those steps that are most receptor-proximal, how such pathways contribute to more quantitative aspects of lymphocyte function is still being elucidated. One of the signaling pathways that appears to be involved in this "tuning" process is controlled by the lipid kinase PI3K. Here we review recent key findings regarding both the triggering/enhancement of PI3K signals (via BCAP and ICOS) as well as their regulation (via PIK3IP1 and PHLPP) and how these signals integrate and determine cellular processes. Lymphocytes display tremendous functional plasticity, adjusting their metabolism and gene expression programs to specific conditions depending on their tissue of residence and the nature of the infectious threat to which they are responding. this website We give an overview of recent findings that have contributed to this model, with a focus on T cells, including what has been learned from patients with gain-of-function mutations in PI3K as well as lessons from cancer immunotherapy approaches.Philodryas olfersii produces similar local effects to Bothrops jararacussu snakebite, which can induce misidentification and bothropic antivenom administration. Antivenom therapy is effective, but has its limitations regarding local damage. Since plants are used in folk medicine to treat snakebite victims, we evaluated the protective properties of Cordia salicifolia and Lafoensia pacari extracts against Philodryas olfersii and Bothrops jararacussu venoms. link2 Preparations pretreated with both extracts inhibited > 90% the B. jararacussu venom-induced neuromuscular blockade, and 52% to 81% the P. olfersii venom-induced blockade. C. salicifolia inhibited the myonecrosis promoted by both venoms; however, L. pacari prevented only the myofilaments hypercontraction. Regarding haemorrhagic activity, C. salicifolia was more effective against B. jararacussu venom, while L. pacari was more effective against P. olfersii venom. On the other hand, for oedema-forming activity the results were the opposite. Considering that both extracts prevented (to different levels) the main manifestations of both snakebites (local symptoms), we endorse further studies involving these plants as coadjuvant in snakebite therapeutics.Venoms of viperid snakes affect mostly hemostasis, while C-type lectin-like proteins (CTLPs), one of the main components of viperid venoms, act as anticoagulants, procoagulants, or agonists/antagonists of platelet activation. However, we have shown earlier that CTLPs from the saw-scaled viper Echis multisquamatus, called emunarecins EM1 and EM2, were able to inhibit nicotinic acetylcholine receptors (nAChRs) in neurons of a pond snail (Lymnaea stagnalis). Here we analysed the structure of the emunarecins by mass spectrometry and report that EM1 and EM2 inhibit fluorescent α-bungarotoxin binding to both muscle-type nAChRs from Torpedo californica and human neuronal α7 nAChRs. EM1 at 23µM and EM2 at 9µM almost completely prevented fluorecsent α-bungarotoxin binding to muscle-type nAChRs. Interaction with human neuronal α7 nAChR was weaker; EM1 at the concentration of 23µM blocked the α-bungarotoxin binding only by about 40% and EM2 at 9µM by about 20%. The efficiency of the EM2 interaction with nAChRs was comparable to that of a non-conventional toxin, WTX, from Naja kaouthia cobra venom. Together with the data obtained earlier, these results show that CTLPs may represent new nAChR ligands.Here we report an unusual case of small bowel obstruction, preluded by an unremarkable presentation of appendicitis. The small bowel obstruction subsequently diagnosed involved deposition of an appendicolith within the small bowel. Radiographic features of this incident are discussed along with its pathomechanics. Surgical management was carried out and is detailed along with advice for the management of retained appendicolith.Schwannomas are generally benign tumors, well delimited, resulting from nerve sheaths that are frequently found in the thorax, mainly in the posterior mediastinum. We report a 58-year-old patient who carried out investigations following the appearance of a large right supraclavicular cervical mass associated with anisocoria and eyelid ptosis, histologically diagnosed as ancient schwannoma, completely removed through a cervicotomic approach without opening the chest.Mayer-Rokitansky-Küster-Hauser syndrome is a congenital malformation that affects the uterus and upper two-thirds of the vagina. Its prevalence is estimated to be 1 in 4500 live births. We present the case of a 19-year-old patient that presented with primary amenorrhea and cyclic abdominal pain. Upon the exploratory laparoscopy, a right rudimentary uterine horn and left unicornuate uterus were found. These two entities were completely separated from each other and from the vaginal vault. In addition, a left ovarian endometrioma was also found. The unicornuate uterus was resected with an intent to resolve the pain. Endometriosis is known to raise the risk of ovarian cancer by 50%. Therefore, a left salpingo-oophorectomy was performed to minimize the risk of ovarian cancer and endometriosis recurrence. In conclusion, ovarian endometriomas should be suspected when obstructive malformations are present with active endometrial remnants. These lesions should be managed appropriately to optimize the postoperative outcomes.Esophageal perforation in liver transplant recipients is a rare phenomenon. link3 We herein report a case of an esophageal perforation due to Sengstaken-Blakemore tube in a liver-transplant recipient diagnosed 6 weeks post-transplant. A 2.5-cm mid-esophageal perforation communicating with large complex fluid collection in the pleural space was found. During endoscopy, 16Fr Salem Sump nasopleural tube (NP) was placed traversing through esophageal perforation into inferior aspect of the collection. Over the following 4 weeks, NP decompressed the cavity, allowed its closure and the tube was slowly retracted. By the end of 4 weeks, NP was removed with follow-up esophagogram showing no extravasation of contrast and a healed perforation. Hence, the esophageal perforation was successfully treated via this unique nonoperative approach without the need for major surgery. In instances of chronic leak with a stable patient, this nonoperative strategy should be considered even in immunocompromised patients.Most studies regarding the use of locking condylar plates in distal femoral fractures have been carried out in tertiary centres. The aim of this case series was to examine outcomes for patients managed in a rural setting and to answer the question 'should we be shipping these patients out to a regional trauma centre?' Recent insertions of condylar locking compression plates (LCPs) at a rural district general hospital were examined. (All used the Synthes LCP Condylar Plate 4.5/5.0 periarticular plating system). Their clinical records and radiology were reviewed to identify failure rates and facilitate discussion of such cases. Of 36 reviewed cases, 4 instances of failure were identified (11%), and their cases are discussed individually herein. This review not only affords the opportunity to discuss cases of failure and to speculate upon their potential causes, but also highlights reassuringly high quality of outcomes for these patients outside of larger teaching hospitals.Abdominal complications after placement of ventriculoperitoneal (VP) shunt are commonly reported but asymptomatic bowel perforation with enterocutaneous fistula (ECF) is rare. This case describes a young male patient who underwent VP shunt for hydrocephalus 10 years ago. He presented with ECF due to the non-functioning abdominal end of the shunt. Patient was managed with laparotomy with fistulectomy with bowel resection and anastomosis. ECF is a rare complication of VP shunt.Trocar-site hernia is an uncommon complication of laparoscopic surgery and can be classified as early-onset, late-onset or special type. Special type hernias usually occur in the early postoperative period and result in evisceration of intra-abdominal contents through all layers of the abdominal wall without an overlying hernia sac. We present a case of special type herniation of the appendix through a 5-mm trocar site in the right iliac fossa following laparoscopic repair of a perforated duodenal ulcer. In this case, herniation occurred after removal of a drain inserted through the trocar site intraoperatively and was treated with emergent open appendicectomy. A number of patient and technical factors may be associated with an increased risk of trocar-site herniation including increasing age, elevated body mass index, increasing trocar size, longer procedure duration and absence of fascial closure. These factors must be borne in mind when planning trocar placement and number to reduce the risk of herniation.A report of true aneurysms is extremely rare. There are only five previous case reports of true aneurysm of the facial artery. In the previously reported cases, there was no case that underwent trapping and surgical excision. In this case report, we describe the procedure of internal trapping before the surgical excision of a huge true aneurysm of the right facial artery for a 79-year-old woman. There was no recurrence of the aneurysm during a 6-month follow-up period.Trigeminal schwannoma is the second most common schwannoma after vestibular schwannoma. Symptoms vary depending on the anatomical structures affected by the tumor, including facial pain, paresthesia, dizziness and ataxia. The primary goals are controlling the symptoms and the maintenance of cranial nerves' integrity perioperatively. We report a 39-year-old lady who was complaining of mild right-sided headache, vision and hearing loss, right facial weakness and dysphagia. CT and MRI showed a large dumbbell-shaped tumor originating from the trigeminal fossa abutting the petrous and cavernous carotid artery and extending to the infratemporal fossa. An image-guided endonasal endoscopic removal was successfully done. Image-guided endonasal endoscopic removal of a trigeminal schwannoma abutting the petrous and cavernous carotid artery and extending to the infratemporal fossa is a safe, effective approach, as it offers excellent visualization, accurate localization and safe dissection of the tumor from the critical anatomical neurovascular structures surrounding it.
