ABSTRACT
AA is a frequent surgical condition that demands urgent intervention. It accounts for approximately 6% of all emergency department visits. Situs inversus is a rare condition in which the orientation of asymmetric organs is a mirror image of normal anatomy. It can be partial (involving either the abdominal or thoracic cavities) or complete (situs inversus totalis: transposition of both abdominal and thoracic organs). SIT is very rare, with an incidence of 1 per 5000 to 10,000 live births. It is inherited in an autosomal recessive pattern with incomplete penetrance. LSAA is very rare and can happen in association with other congenital abnormalities such as situs inversus, midgut malrotation (MM), or a usually long right-sided appendix projecting into the left lower quadrant. SIT is responsible for greater than 67% of left-sided appendicitis cases. Due to atypical clinical presentation, the diagnosis of AA can be difficult and often delayed. Hence, a complete medical history, physical examination, laboratory tests, and imaging tools are necessary to reach a correct diagnosis in a timely manner and prevent complications like abscesses, perforations, and peritonitis. We report a case of a 50-year-old male with symptoms of left lower abdominal pain along with fever, nausea, vomiting, and loose stools that were later diagnosed as LSAA in the setting of SIT.
ABSTRACT
Introduction and importance: Sinonasal inverted papilloma is a rare benign tumor of the nasal cavity and paranasal sinuses (PNS). Radiological evaluation is the key to management. Case presentation: A 46-year-old male presented with complaints of right nasal congestion and occasional bleeding for 4 months. During anterior rhinoscopy, a pinkish fleshy mass occupying the right nasal cavity was seen. X-ray and computed tomography (CT) PNS view showed opacification in the right nasal cavity and maxillary sinus. An MRI of the nose and PNS revealed a peculiar convoluted striated/cerebriform pattern. Histopathology report described the features of an inverted papilloma. The patient underwent endoscopic removal of the mass under general anesthesia. Surgical resection of the tumor was performed along with adjacent normal mucosal tissues. The patient recovered well and was followed-up for recurrence. Clinical discussion: Sinonasal inverted papilloma is commonly found in males in their fifth to sixth decade of life. A CT scan is the initial modality of choice to evaluate the extent of the disease. MRI is superior to CT in distinguishing tumors from other conditions as well as to evaluate soft tissue extensions. Involvement of the frontal sinus is a risk factor for recurrence. The first option for treating an inverted papilloma is complete surgical removal with the adjacent uninvolved mucosa. Conclusion: In a biopsy-proven case, radiological assessments like CT and MRI play a pivotal role in studying the typical morphology, delineating the extension, and detecting recurrence.
ABSTRACT
Immunoglobulin A nephropathy is the most prevalent form of primary glomerulonephritis. Case presentation: A 33-year-old military male presented with complaints of fever, headache, myalgia, chills, and haematuria for 10 years. His lab results showed elevated serum creatinine levels and proteinuria. A renal biopsy was done which was consistent with a diagnosis of immunoglobulin A nephropathy. He was managed with antihypertensive, including angiotensin-converting enzyme inhibitors, steroids and immunosuppressants, and Omega-3 fatty acids. There was remission of the symptoms and the patient's serum creatinine and sonogram findings returned to baseline. Conclusion: Routine follow-up along with the appropriate use of medications can limit disease complications and progression.
ABSTRACT
Wheat is highly prone to terminal heat stress (HS) under late-sown conditions. Delayed- sowing is one of the preferred methods to screen the genotypes for thermotolerance under open field conditions. We investigated the effect of terminal HS on the thermotolerance of four popular genotypes of wheat i.e. WR544, HD2967, HD2932, and HD2285 under field condition. We observed significant variations in the biochemical parameters like protein content, antioxidant activity, proline and total reducing sugar content in leaf, stem, and spike under normal (26 ± 2°C) and terminal HS (36 ± 2°C) conditions. Maximum protein, sugars and proline was observed in HD2967, as compared to other cultivars under terminal HS. Wheat cv. HD2967 showed more adaptability to the terminal HS. Differential protein-profiling in leaves, stem and spike of HD2967 under normal (26 ± 2°C) and terminal HS (36 ± 2°C) showed expression of some unique protein spots. MALDI-TOF/MS analysis showed the DEPs as RuBisCO (Rub), RuBisCO activase (Rca), oxygen evolving enhancer protein (OEEP), hypothetical proteins, etc. Expression analysis of genes associated with photosynthesis (Rub and Rca) and starch biosynthesis pathway (AGPase, SSS and SBE) showed significant variations in the expression under terminal HS. HD2967 showed better performance, as compared to other cultivars under terminal HS. SSS activity observed in HD2967 showed more stability under terminal HS, as compared with other cultivars. Triggering of different biochemical parameters in response to terminal HS was observed to modulate the plasticity of carbon assimilatory pathway. The identified DEPs will enrich the proteomic resources of wheat and will provide a potential biochemical marker for screening wheat germplasm for thermotolerance. The model hypothesized will help the researchers to work in a more focused way to develop terminal heat tolerant wheat without compromising with the quality and quantity of grains.
ABSTRACT
Drought is one of the limiting environmental factors that affect crop production worldwide. Understanding the molecular mechanism of drought stress is the key to developing drought tolerant crop. In this experiment we performed expression profiling of tomato plants under water deficit conditions using microarray technology. The data set we generated (available in the NCBI/GEO database under GSE22304) has been analyzed to identify genes that are involved in the regulation of tomato's responses to drought.
