RESUMO

Background The carpal tunnel is a groove that spans the palm as a 'U.' The ulnar and radial sides of the wrist are made up of the scaphoid tubercle and trapezium while the palmar aspect is made up of carpal bones. Our study aimed to see whether there were differences in carpal tunnel size between men and women. Material and methods The study was conducted on 65 healthy adults, 13 (20%) were males and 52 (80%) were females (both non-pregnant and pregnant). Inclusion criteria were healthy adults and bilaterally symmetrical limbs. Exclusion criteria were chronic disease, diabetes, hypertension, immunological disorders, any visible abnormalities, and a history of upper extremity pain on either side. A high-resolution ultrasound machine with a linear transducer was used to perform an ultrasound scan of the carpal tunnel. The anteroposterior dimension was measured at the midline, or along the axis of the middle finger, and the transverse diameter was measured at the midpoint of the flexor retinaculum. The cross-sectional area of the tunnel was measured at its largest diameter within the carpal tunnel. All the dimensions were measured in centimeters. Results The mean transverse diameter of the right side was 1.824 ± 0.223 cm (p-value 0.002) and of the left side was 1.742 ± 0.197 cm (p-value 0.004). The mean cross-sectional area of the carpal tunnel on the right side was 1.417 ± 0.379 cm2 (p-value 0.008) and on the left side was 1.306 ± 0.303 cm2 (p-value 0.004), respectively. Age, sex, weight, and BMI were discussed. The carpal tunnels of females were found to be comparatively squarer and smaller than those of males. Conclusion The transverse diameter and cross-sectional area of the carpal tunnel and their correlation with carpal tunnel syndrome are predicted by age, sex, weight, and BMI. Both sexes had the same wrist ratio.

RESUMO

Lectins are non-immunological carbohydrate-binding proteins classified on the basis of their structure, origin, and sugar specificity. The binding specificity of such proteins with the surface glycan moiety determines their activity and clinical applications. Thus, lectins hold great potential as diagnostic and drug discovery agents and as novel biopharmaceutical products. In recent years, significant advancements have been made in understanding plant and microbial lectins as therapeutic agents against various viral diseases. Among them, mannose-specific lectins have being proven as promising antiviral agents against a variety of viruses, such as HIV, Influenza, Herpes, Ebola, Hepatitis, Severe Acute Respiratory Syndrome Coronavirus-1 (SARS-CoV-1), Middle Eastern Respiratory Syndrome Coronavirus (MERS-CoV) and most recent Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2). The binding of mannose-binding lectins (MBLs) from plants and microbes to high-mannose containing N-glycans (which may be simple or complex) of glycoproteins found on the surface of viruses has been found to be highly specific and mainly responsible for their antiviral activity. MBLs target various steps in the viral life cycle, including viral attachment, entry and replication. The present review discusses the brief classification and structure of lectins along with antiviral activity of various mannose-specific lectins from plants and microbial sources and their diagnostic and therapeutic applications against viral diseases.

RESUMO

INTRODUCTION:  Correct localization of the sacral hiatus is essential for administering a successful caudal epidural block. The present study was undertaken to find out the anatomical variations of sacral hiatus by a metrical method so that it could help anaesthesiologists in the clinical field. MATERIALS AND METHODS: The study was performed on 140 (83 male and 57 female) adult human sacra. Various parameters of the sacrum studied were as follows: the shape of the hiatus, length of the sacral hiatus, transverse width at the base and anteroposterior diameter at the level of the apex. For each parameter, the mean value (calculated in mm), standard deviation, range and percentage of bones identified correctly were calculated. RESULTS: Various shapes of sacral hiatus were observed, including inverted "U" in 73 (52.14%), inverted "V" in 33 (23.57%), irregular in 10 (7.14%), elongated in 10 (7.14%) and dumbbell-shaped in 12 (8.57%). Absent sacral hiatus was observed in two (1.43%) specimens. The mean value for the length of sacral hiatus from the apex to the midpoint of the base was found to be 23.26 mm in males and 22.38 mm in females. However, the parameter was found to be statistically not significant. The mean value for transverse width at the base of hiatus was found to be 14.19 mm in males and 13.54 mm in females. The mean value for the anteroposterior diameter of the sacral canal at the apex was found to be 4.57 mm in males and 4.32 mm in females. Both the above parameters were found to be statistically not significant. SUMMARY AND CONCLUSION: The anatomical knowledge of sacral hiatus and its variations are important in caudal epidural anaesthesia, and it may improve the success rate of caudal epidural anaesthesia.

RESUMO

The global malnutrition burden imparts long-term developmental, economic, social, and medical consequences to individuals, communities, and countries. The current developments in biotechnology have infused biofortification in several food crops to fight malnutrition. However, these methods are not sustainable and suffer from several limitations, which are being solved by the CRISPR-Cas-based system of genome editing. The pin-pointed approach of CRISPR-based genome editing has made it a top-notch method due to targeted gene editing, thus making it free from ethical issues faced by transgenic crops. The CRISPR-Cas genome-editing tool has been extensively used in crop improvement programs due to its more straightforward design, low methodology cost, high efficiency, good reproducibility, and quick cycle. The system is now being utilized in the biofortification of cereal crops such as rice, wheat, barley, and maize, including vegetable crops such as potato and tomato. The CRISPR-Cas-based crop genome editing has been utilized in imparting/producing qualitative enhancement in aroma, shelf life, sweetness, and quantitative improvement in starch, protein, gamma-aminobutyric acid (GABA), oleic acid, anthocyanin, phytic acid, gluten, and steroidal glycoalkaloid contents. Some varieties have even been modified to become disease and stress-resistant. Thus, the present review critically discusses CRISPR-Cas genome editing-based biofortification of crops for imparting nutraceutical properties.

RESUMO

Background The traditional coronary calcium score (CCS) is a time-tested tool for the evaluation of coronary atherosclerosis and predictor of future cardiovascular events. Non-traditional tools can also have a value in predicting and detecting subclinical coronary artery disease (CAD). Methods We studied the role of CCS, the traditional CAD risk predictor, and the less-recognized, non-traditional risk factors, i.e. epicardial fat volume (EFV) and thoracic extracoronary calcium (ECC), to assess the degree of subclinical CAD. In this cross-sectional observational study, we included 950 Indian patients (suspected to have CAD). Coronary computed tomography angiography was performed. Estimation of CCS, EFV and thoracic ECC was done. Results A CCS of 0 was seen in 583 patients (61.4%). Of these, 492 patients had normal coronary angiogram but 91 patients had CAD. The median values of EFV were statistically significantly higher in the 'CAD present and CCS 0' group compared to the 'CAD absent and CCS 0' group (p<0.001). The presence of thoracic ECC involving at least a single site was seen in only 6 of these 91 patients. When both EFV and CCS were considered together for the detection of CAD, the sensitivity and negative predictive value (NPV) were improved compared to either of these in isolation. When ECC was taken together with CCS and EFV, no further improvement in sensitivity or NPV was observed. Conclusion The combined use of traditional CCS along with non-traditional EFV may guide us in better profiling cardiovascular risk and supplement the various traditional cardiovascular risk factors/scores.

RESUMO

BACKGROUND & AIMS: Diabetes mellitus (DM) and thyroid disorders are the most common endocrine disorders in clinical practice. Unrecognized thyroid disorders have an adverse effect on metabolic functions. The aim of the study is to demonstrate the prevalence of thyroid disorders in individuals with diabetes mellitus. METHODS: A prospective observational study, conducted at Sree Sidhi Vinayaka Diabetic Center, between September 2013 to December 2019. A total of 5037 patients attended the outpatient clinic, among which 2470 met the inclusion criteria. All patients underwent a clinical and laboratory evaluation. RESULTS: A total of 2321 individuals with diabetes had consented to be the part of the study, 102 had Type 1 diabetes mellitus (T1DM) and 2219 Type 2 diabetes mellitus (T2DM). The mean age was 48.4 ± 10.7, among which 1128 females and 1193 are males. 79.9% (1853) individuals with diabetes were euthyroid; 13.8% (321) subclinical hypothyroidism; 3.4% (79) clinical hypothyroidism, and 2.9% (68) were having hyperthyroidism. 14.1% of T2DM had subclinical hypothyroidism, in contrast, clinical hypothyroidism was common in T1DM (6.9%). CONCLUSION: A high index of suspicion for thyroid dysfunction in diabetics should be considered to screen for thyroid function in them for early detection and effective management of both the conditions.

RESUMO

BACKGROUND: Class III plant peroxidases play important role in a number of physiological processes in plants such as lignin biosynthesis, suberization, cell wall biosynthesis, reactive oxygen species metabolism and plant defense against pathogens. Peroxidases are also of significance in several industrial applications. In view of this, the production and identification of novel peroxidases having resistance towards temperature, pH, salts is desirable. OBJECTIVE: The objective of the present work was to clone and characterize a novel plant peroxidase suitable for industrial application. METHODS: A full length cDNA clone of lemon peroxidase was isolated using PCR and RACE approaches, characterized and heterologously expressed in Escherichia coli using standard protocols. The expressed peroxidase was purified using Ni-NTA agarose column and biochemically characterized using standard protocols. The peroxidase was also in-silico characterized at nucleotide as well as protein levels using standard protocols. RESULTS: A full length cDNA clone of lemon peroxidase was isolated and expressed heterologously in E. coli. The expressed recombinant lemon peroxidase (LPRX) was activated by in-vitro refolding and purified. The purified LPRX exhibited pH and temperature optima of pH 7.0 and 50°C, respectively. The LPRX was found to be activated by metal ions (Na+, Ca2+, Mg2+ and Mn2+) at lower concentration. The expressional analysis of the transcripts suggested involvement of lemon peroxidase in plant defense. The lemon peroxidase was in silico modelled and docked with the substrates guaiacol, and pyrogallol and shown the favourability of pyrogallol over guaiacol, which is in agreement with the in-vitro findings. The protein function annotation analyses suggested the involvement of lemon peroxidase in the phenylpropanoid biosynthesis pathway and plant defense mechanisms. CONCLUSION: Based on the biochemical characterization, the purified peroxidase was found to be resistant towards the salts and thus, might be a good candidate for industrial exploitation. The in-silico protein function annotation and transcript analyses highlighted the possible involvement of the lemon peroxidase in plant defense response.

RESUMO

Mucormycosis is a fungal infection caused by fungi of order mucorales. It is most commonly seen in patients with an impaired immune system due to any cause. Gastrointestinal mucormycosis is the least frequent type and may be a primary disease or a feature of generalized mucormycosis. Angioinvasion is the hallmark feature of mucormycosis, leading to bowel infarction which is the responsible for the most common clinical complaint of pain, and is also responsible for most of the imaging findings in this disease. The stomach is most commonly involved organ in the gastrointestinal tract and pneumatosis and lack of gastric wall enhancement are the most common imaging findings. Areas of bowel wall thickening and/ or lack of enhancement are seen in small bowel mucor and perforation can occur due to ischemia. Colonic mucor can present with mural thickening, or complete lack of definition or 'disappearance' of bowel wall with associated air containing collections. Mucormycosis affecting the bowel has a high mortality rate and early recognition and intervention may improve patient outcomes significantly. It should be suspected in immunosuppressed patients with imaging findings of unexplained bowel ischemia, infarction and/or pneumatosis without any obvious visible vascular thrombus.

RESUMO

Topoisomerases are reported to resolve the topological problems of DNA during several cellular processes, such as DNA replication, transcription, recombination, and chromatin remodeling. Two types of topoisomerases (Topo I and II) accomplish their designated tasks by introducing single- or double-strand breaks within the duplex DNA molecules, and thus maintain the proper structural conditions of DNA to release the topological torsions, which is generated by unwinding of DNA to access coded information, in the course of replication, transcription, and other processes. Both the topoisomerases have been looked at as crucial targets against various types of cancers such as lung, melanoma, breast, and prostate cancers. Conceptually, targeting topoisomerases will disrupt both DNA replication and transcription, thereby leading to inhibition of cell division and consequently stopping the growth of actively dividing cancerous cells. Since the discovery of camptothecin (an alkaloid) as an inhibitor of Topo I in 1958, a number of derivatives of camptothecin were developed as potent inhibitors of Topo I. Two such derivatives of camptothecin, namely, topotecan and irinotecan, have been commonly used as US Food and Drug Administration (FDA) approved drugs against Topo I. Similarly, the first Topo II inhibitor, namely, etoposide, an analogue of podophyllotoxin, was developed in 1966 and got FDA approval as an anti-cancer drug in 1983. Subsequently, several other inhibitors of Topo II, such as doxorubicin, mitoxantrone, and teniposide, were developed. These drugs have been reported to cause accumulation of cytotoxic non-reversible DNA double-strand breaks (cleavable complex). Thus, the present review describes the anticancer potential of plant-derived secondary metabolites belonging to alkaloids, flavonoids and terpenoids directed against topoisomerases. Furthermore, in view of the recent advances made in the field of computer-aided drug design, the present review also discusses the use of computational approaches such as ADMET, molecular docking, molecular dynamics simulation and QSAR to assess and predict the safety, efficacy, potency and identification of these potent anti-cancerous therapeutic molecules.

RESUMO

BACKGROUND: Periodontal Disease (PD) is associated with complications of diabetes. Control of the PD reduces glycated hemoglobin (HbA1c) level. This study aimed to evaluate the relationship of PD with duration, severity of diabetes and eGFR. MATERIAL AND METHOD: A Prospective observational study conducted at Sidhi Vinayaka Hospitals (SVH) Sangareddy during the period of January 2014 to December 2019. Total 1436 patients with a definite diagnosis of type 2 diabetes (T2DM), between the ages of 45-60 years were included. They were classified according to CPITN score for PD and compared against the variables. RESULTS: A total of 1436 consecutive outpatients attending to SVH were included. Among them 662 (46.1%) were males and 774(53.9%) were females. The mean age of the patients was 48.3(SD ± 10.62) and mean duration of diabetes was 2.9(SD ± 4.18). The mean fasting blood glucose was 198.5(SD ± 85), mean post prandial blood glucose was 277.2 (SD ± 107.7) and mean HBA1c was 9.98% (SD ± 2.6). Among the study group 1198 (83.4%) had none/mild (Grade I) PD, 192(13.4%) had moderate/severe (Grade II) PD and 46(3.2%) were completely edentulous (Grade III). CONCLUSION: There is a linear correlation between PD and age of patient, duration of diabetes, eGFR and level of glycemic status among rural population with T2DM.

RESUMO

Protein folding is the process by which a polypeptide chain acquires its functional, native 3D structure. Protein misfolding, on the other hand, is a process in which protein fails to fold into its native functional conformation. This misfolding of proteins may lead to precipitation of a number of serious diseases such as Cystic Fibrosis (CF), Alzheimer's Disease (AD), Parkinson's Disease (PD), and Amyotrophic Lateral Sclerosis (ALS) etc. Protein Quality-control (PQC) systems, consisting of molecular chaperones, proteases and regulatory factors, help in protein folding and prevent its aggregation. At the same time, PQC systems also do sorting and removal of improperly folded polypeptides. Among the major types of PQC systems involved in protein homeostasis are cytosolic, Endoplasmic Reticulum (ER) and mitochondrial ones. The cytosol PQC system includes a large number of component chaperones, such as Nascent-polypeptide-associated Complex (NAC), Hsp40, Hsp70, prefoldin and T Complex Protein-1 (TCP-1) Ring Complex (TRiC). Protein misfolding diseases caused due to defective cytosolic PQC system include diseases involving keratin/collagen proteins, cardiomyopathies, phenylketonuria, PD and ALS. The components of PQC system of Endoplasmic Reticulum (ER) include Binding immunoglobulin Protein (BiP), Calnexin (CNX), Calreticulin (CRT), Glucose-regulated Protein GRP94, the thiol-disulphide oxidoreductases, Protein Disulphide Isomerase (PDI) and ERp57. ER-linked misfolding diseases include CF and Familial Neurohypophyseal Diabetes Insipidus (FNDI). The components of mitochondrial PQC system include mitochondrial chaperones such as the Hsp70, the Hsp60/Hsp10 and a set of proteases having AAA+ domains similar to the proteasome that are situated in the matrix or the inner membrane. Protein misfolding diseases caused due to defective mitochondrial PQC system include medium-chain acyl-CoA dehydrogenase (MCAD)/Short-chain Acyl-CoA Dehydrogenase (SCAD) deficiency diseases, hereditary spastic paraplegia. Among therapeutic approaches towards the treatment of various protein misfolding diseases, chaperones have been suggested as potential therapeutic molecules for target based treatment. Chaperones have been advantageous because of their efficient entry and distribution inside the cells, including specific cellular compartments, in therapeutic concentrations. Based on the chemical nature of the chaperones used for therapeutic purposes, molecular, chemical and pharmacological classes of chaperones have been discussed.

RESUMO

AIM AND OBJECTIVES: Aim of this study was to compare prospective effectiveness of arthrocentesis of temporomandibular joint by single- and double-needle technique in central India population. MATERIALS AND METHODS: Out of 230 patients, 500 joints were included in the study and were randomly selected into two groups: single needle and double needle. Follow-up of patients were done as 1 week, 1 and 3 months. (The statistical analysis was done using SPSS [Statistical Package for Social Sciences] Version 15.0 Statistical Analysis Software). RESULTS: Both techniques were equally effective at reducing pain and increasing the maximal mouth opening. The single-needle technique was easier to perform and required a shorter operative time (P < 0.01). CONCLUSION: The results obtained indicate that single versus double arthrocentesis techniques were equally effective in reducing the pain and increasing the mouth opening and reducing the clicking sound. However, single-needle technique was easier to perform and required a shorter operative time.

RESUMO

OBJECTIVE: We studied the correlation of quantified epicardial fat with severity of coronary artery disease in patients [suspected cases of coronary artery disease (CAD)] referred for computed tomography (CT) coronary angiography and established cutoffs for epicardial fat volume (EFV) for the presence of CAD and obstructive CAD. METHODS: A prospective cum retrospective cross-sectional observational study was carried out on 950 Indian subjects (suspected cases of CAD) who were referred for coronary CT in the year 2013-2016. EFV was quantified using semiautomatic technique on multidetector coronary CT angiography. The presence of atherosclerotic plaques and degree of stenosis was assessed on coronary CT angiography scans. The correlation between quantified EFV and degree of stenosis was assessed. Multivariate analysis was also performed. RESULTS: A higher quantity of epicardial fat is found in patients with increasing severity of coronary artery stenosis. The EFV cutoff for the presence of CAD and obstructive CAD are 49.75 and 67.69 mL with area under the curve, sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of 0.68, 81%, 45.9%,58.24%, 72.2%, and 62.84% and 0.709, 64.9%, 66.4%, 35.84%, 86.55%, and 66%, respectively. EFV correlates with age, weight, and body mass index (BMI). Multivariate analysis revealed EFV to be an independent risk factor for the presence of CAD. CONCLUSIONS: Higher quantities of EFV are found in patients with greater degree of coronary artery stenosis. EFV correlates with age, weight, and BMI. EFV is an independent risk factor for CAD.

RESUMO

In patients with pulmonary atresia and ventricular septal defect (PA/VSD), a coronary artery being the primary source of pulmonary blood flow is a rare entity. We describe two cases of PA/VSD with coronary-to-pulmonary artery fistula with emphasis on the role of Computed Tomographic Angiography (CTA) in depicting all the sources of pulmonary blood supply, to predict surgical management and need for unifocalization of Major Aortopulmonary Collateral Arteries (MAPCA's).

RESUMO

Abernethy malformation, also known as congenital extrahepatic portosystemic shunts (CEPS) is a rare clinical entity and manifests with different clinical symptoms. CEPS are abnormalities of vascular development where there is shunting of portal blood into the systemic venous system. Multidetector computed tomography (MDCT) is a fast and effective modality for evaluation of CEPS. CT displays all the information desired by the surgeon as well as the clinician including the anatomy of the splenic and superior mesenteric veins, size and site of the shunt, presence or absence of the portal vein radicles, and helps to plan the therapy and even the follow-up of these patients. Contrast-enhanced magnetic resonance imaging (MRI) has also emerged as a promising tool for the evaluation of liver lesions associated with the malformation. The Radiologist should be aware of the various imaging appearances of this entity including its complications. In this article, we describe the imaging appearances of CEPS, their complications, and their imaging appearances on CT and MRI. We have also described various associated anomalies.

Ectopic pancreas is a rare entity where the pancreatic tissue has no anatomic and vascular contact with the main body of the pancreas and has its own duct system and vascular supply. A detailed clinical report with contrast-enhanced computed tomography (CT) and endoscopic ultrasonography (EUS) imaging findings of a 40-year-old male came with vague symptoms. CT showed a well-defined homogeneously enhancing mass lesion in the duodenojejunal (DJ) flexure. EUS revealed a well-defined hypoechoic mass lesion in the submucosal layer of the DJ flexure. Surgical resection of the mass was performed, and histopathological examination of specimen confirmed the pancreatic tissues. Here, we have described the CT and EUS imaging features which can help to differentiate the ectopic pancreas from the gastrointestinal submucosal tumours.

RESUMO

BACKGROUND: Experience and literature regarding complications of lower extremity compartment syndrome led us to hypothesize that delayed diagnosis and limb loss are potentially preventable events. Clinical examination does play a role, but quantification of compartment pressure reading serves as confirmation and determines the need for surgical intervention and provides the only objective data in case of conflict. METHODS: We performed a prospective study of all cases of closed tibial fractures presenting to our trauma centre over a 3-year period (January 2009-June 2012). Variables reviewed included intra-compartmental pressure readings, location of the fracture and development of subsequent compartment syndrome requiring fasciotomy. Patients were divided into (1) Group A - proximal tibial fracture, (2) Group B - diaphyseal fracture and (3) Group C - Pilon fracture. Values of the injured and uninjured leg were taken and the data analyzed using SPSS version 22. RESULTS: 168 (41 females and 127 males) cases were analyzed. Mean pressure readings of the fractured limb were higher in Group A compared to the other groups. The mean difference in pressure values between the injured and uninjured limb recorded were of 15.1 mm Hg (Group A), 13.8 mm Hg (Group B) and 13.3 mm Hg (Group C). Patients who eventually underwent fasciotomy were 5 (10.8%) in Group A, 8 (10.3%) in Group B and 3 (6.8%) in Group C, and had initial baseline pressure difference of >18.5 mm Hg. CONCLUSION: These data underscore the importance of routine recording of initial intra-compartmental pressure and relation of difference in compartmental pressure between injured and uninjured limb to eventual development of compartment syndrome requiring fasciotomy.

RESUMO

Coronary artery anomalies occur in less than 1 % of the general population. With the advent of multidetector rows and 3D reconstruction, multidetector computed tomography has emerged as the modality of choice in the delineation of the complex coronary anatomy and diagnosis of coronary artery anomalies, helping in the institution of appropriate therapy. We report a case of coronary cameral fistula of the left anterior descending artery to the right ventricle, which was closed by an Amplatzer vascular plug. Coronary CT angiography was used to evaluate the patient prior to the procedure to locate the placement site for the vascular plug.
