During a spontaneous and autonomous study, we assessed the ultrasound finding of lymphadenopathy after BNT162b2 Pfizer vaccine. We enrolled 18 patients with 58 lymphadenopathies: in 10 patients, they were in the laterocervical side, while in 8 patients in the axillar site. The largest diameter was 14 mm with a range from 7 to 16 mm (median value = 10 mm). In the same patient, we found different ultrasound nodal findings. A total of 25 nodes showed eccentric cortical thickening with wide echogenic hilum and oval shape. In total, 19 nodes showed asymmetric eccentric cortical thickening with wide echogenic hilum and oval shape. Overall, 10 nodes showed concentric cortical thickening with reduction in the width of the echogenic hilum and oval shape. A total of four nodes showed huge reduction and displacement of the echogenic hilum and round or oval shape. No anomaly was found at the Doppler echocolor study. In conclusion, eccentric cortical thickening with wide echogenic hilum and oval shape, asymmetric eccentric cortical thickening with wide echogenic hilum and oval shape, concentric cortical thickening with reduction in the width of the echogenic hilum and oval shape, and a huge reduction and displacement of the echogenic hilum and round shape are the features that we found in post BNT162b2 Covid-19 Vaccine lymphadenopathies.

Objective: To study the spectrum of histopathological lesions found on surgically resected gallbladder to quantify the various abnormalities in gallbladder specimen. Methodology: A descriptive observational study was carried out from Nov 2017 to Oct 2021. All the patients undergoing emergency and elective cholecystectomy regardless of age and sex were included in the study. After cholecystectomy, gallbladder specimen along with history and ultrasound findings was sent for histopathology to our own institution. Department of histopathology has the standardized method to process the gallbladder specimens. Demographic data along with diagnosis, ultrasound finding and histopathology report were collected and analyzed with Excel 2019. Results: Total number of patients in this study was 395, out of which 93 patients were male and 302 patients were female. Average age of our patients was 43.05± 13 years. Acute calculus cholecystitis was found in 55 (13.92%) patients, 298 (75.44) patents had chronic calculus cholecystitis, empyema was found in 15 (3.80) patients, cholestrolosis was found in 5 (1.27%) patients, gallbladder polyp was found in 02 (0.51%) patients, gangrenous gall bladder was found in 01 (0.25%) patient and adenocarcinoma in situ was found in 01 (0.25%) patient. Conclusion: Our study shows that, chronic cholecystitis is the most common presentation followed by acute cholecystitis in surgically resected gallbladders. Females are predominantly suffering from the gallbladder diseases. The frequency of malignant lesion was very low. Keywords: Gallbladder-histopathology, Acute Cholecystitis, Chronic Cholecystitis, Gallstones.

Background: Mandible also known as the largest and inferior, primary facial bone of the face giving a curved shape to it. It changes its shape and gives variations to the bony structure of the face from birth till older age. Mental foramen is known as the ventage of the mandible and is an important mark of the face for carrying out many diagnostics and surgical processes along with anesthetic procedures of the face. Thus, the present study is designed with an aim to get insight knowledge of position and shape of mental foramen in dry adult human mandible.Methods: Totally, 60 bones were studied in 2 years duration. The study was carried out in the Department of Anatomy of Geetanjali Medical College and Hospital and Rabindranath Medical College. The position of mental foramen was studied using an instrument known as digital Vernier Calliper (in mm) while shape was analyzed visually. Position of mental foramen was calculated using Statistical package for social sciences (SPSS) software.Results: The present study showed that the position of mental foramen from symphysis menti and posterior border of ramus of mandible was more from right side than left side and found to be insignificant while position of mental foramen from inferior border of body of mandible was more from left side than right side and found to be insignificant for right side while significant for left side. The shape of mental foramen from right side was found to be (Oval shape- 68.33% and round shape – 31.66%) while for left side was found to be (Oval shape- 71.66% and round shape – 28.33%).Conclusions: Hence, mental foramen plays a pivotal role in performing major facial surgeries and is an important landmark for several facial procedures performed.

Background: We aimed to investigate possible association between the HLA-B*35 allele and peripheral arthritis, tenosynovitis and enthesitis. Methods: Ultrasound of peripheral joints and tendons was performed in 72 HLA-B*35 positive patients with preliminary diagnosis of undifferentiated axial form of spondyloarthitis and joint and tendon pain. Patients with other known types of axial and peripheral spondyloarthritis were excluded as well as patients with other known types of arthritis. Results: Pathological changes were found in the joints of 33 (46%) patients and on the tendons in 13 (18%) patients. The most common ultrasound findings were joint effusion and synovial proliferation with positive power Doppler signal grade 1. The most common ultrasound finding in patients with painful tendons was tenosynovitis. A higher disease activity and an increased incidence of elevated CRP (≥5 mg/L) were more often observed in the group with positive ultrasound findings. Conclusion: In this study, we showed that the HLA-B*35 allele could be a potential risk factor for developing peripheral arthritis, but not for tenosynovits and enthesitis in patients with the undifferentiated axial form of spondyloarthritis. This result may influence the follow up of these patients, especially since it gives us an opportunity to consider the use of different types of DMARDs in the treatment of these patients.

In this paper, we conduct an experimental and computational study about trailing edge cooling of a gas turbine blade with perforated blockages with inclined holes. The internal cooling passage is modeled as a wide square channel with 2 parallel blockages. There are 7 inclined holes in each blockages. The holes have an inclined angle of 30°, and the adjacent impingement holes have opposite orientations with each other, so that both up and down wall could be cooled. There are 2 patterns of configurations. The basic one has round shape holes with a diameter of 20 mm (D). The second one has oval shape hole which is made up of two parallel lines with the length of 20mm and two opposite semicircle with a diameter of 20 mm. This design is aimed at enlarging the opening area of the blockages. The height of the cooling channel is 2D and the width of the cooling channels is 20D. The space between each hole is 3D. The distance between two blockages is 5D. The main purpose of this paper is to study the effect of holes shape on heat transfer performance, both heat transfer coefficient and friction factor are evaluated. Heat transfer coefficient is measured using transient liquid crystal method. And pressure dissipation is measured by three holes probe. The Reynolds Number ranges from 10000 to 20000. The result shows that round shape structure has the highest average heat transfer coefficient as well as the highest friction factor. And oval shape structure has the lowest average heat transfer as well as the lowest friction factor. The main reason of this phenomenon is opening area ratio. Oval shape structure has bigger opening area and lower flow resistance. Round shape structure has a lower opening area ratio which result in stronger impingement flow. To investigate the flow characteristic of these structures in detail, numerical simulations was conducted. The mesh for each structure contains approximately 4 million cells. The result shows a clear picture of flow inside the inclined holes.

Background: Laparoscopic cholecystectomy is a commonly performed procedure in general surgical practise, which can sometimes be tedious and can have high morbidity. Ultrasound abdomen is a routinely performed radiological investigation for every case of cholecystectomy. This study intends to find correlation between the ultrasound findings and the perceived difficulty during surgery.Methods: This is a prospective study of 100 patients who underwent cholecystectomy after a preoperative ultrasound. Difficult cholecystectomies were defined and sonographic findings and intraoperative difficulties recorded and tabulated.Results: Fifty one cholecystectomies were classified as difficult cholecystectomy (20 converted to open procedure and 31 took more than 90 min to complete laparoscopically). The commonest ultrasound finding that was encountered was multiple calculi (62%) followed by gallbladder (GB) wall thickness of >4 mm (33%), stone size >1 cm (22%), contracted GB (17%), intrahepatic biliary radicals (IHBR) dilatation (15%) and the least common finding was empyema of the gallbladder seen in 7% of the cases.Conclusions: This study is a reflection of surgeries performed by a single team over 3 years which included 100 cases. It was started with an idea to identify the findings on a preoperative ultrasound that predicted a difficult cholecystectomy (laparoscopic or open). In our experience we found that empyema GB, pericholecystic fluid, IHBR dilatation and wall thickness of GB are excellent predictors of a difficult cholecystectomy.

Unripe banana fruit of Musa acuminata (Musa AAA; Hom Khieo) and Musa sapientum L. (Musa ABB; Namwa) growing in Chiang Rai (Thailand) were used for extraction. The yield of the starches was 16.88% for Hom Khieo (HK) and 22.73% for Namwa (NW) based on unripe peeled banana fruit. The amylose contents of HK and NW were 24.99% and 26.23%, respectively. The morphology of starch granules was oval shape with elongated forms for large granules and round shape for small granules. The HK and NW showed B-type crystalline structure and the crystallinities were 23.54% and 26.83%, respectively. The peak temperature of gelatinization was around 77 °C and the enthalpy change (ΔH) was 3.05 and 7.76 J/g, respectively. The HK and NW banana starches showed 1.27 ± 0.12 g/g and 1.53 ± 0.12 g/g water absorption capacity, and 1.22 ± 0.11 g/g and 1.16 ± 0.12 g/g oil absorption capacity, respectively. The swelling power of the banana starches was 17.23 ± 0.94 g/g and 15.90 ± 0.15 g/g, respectively, and the percentage of solubility in water showed 26.43 ± 2.50 g/g and 20.54 ± 0.94 g/g, respectively. The banana starches showed very poor flow character. The HK and NW starches have the potential to be used in powder base preparations with no effect on the sensory texture of the product at 15% w/w maximum.

Relatively few data on the development of the amygdaloid complex are available only at the light microscopic level (1-3). The existence of just general morphological criteria requires the performance of other investigations in particular ultrastructural in order to obtain new and more detailed information about the changes in the amygdaloid complex during development.The prenatal and postnatal development of rat amygdaloid complex beginning from the 12th embrionic day (ED) till the 33rd postnatal day (PD) has been studied. During the early stages of neurogenesis (12ED), the nerve cells were observed to be closely packed, small-sized, with oval shape. A thin ring of cytoplasm surrounded their large nuclei, their nucleoli being very active with various size and form (Fig.1). Some cells possessed more abundant cytoplasm. The perikarya were extremely rich in free ribosomes. Single sacs of the rough endoplasmic reticulum and mitochondria were observed among them. The mitochondria were with light matrix and possessed few cristae. Neural processes were viewed to sprout from some nerve cells (Fig.2). Later the nuclei were still comparatively large and with various shape.
