3D printing plays a crucial role in the development of controlled porous architectures of scaffolds for cartilage tissue regeneration. In the present study, different compositions of chitosan-gelatin-alginate composite scaffolds with controlled porosity and architectures were 3D printed. To obtain the desired scaffold, an in-house 3D paste extruder printer was developed, which is capable of printing porous composite chitosan hydrogel scaffolds of desired architecture layer by layer. Stereolithography (STL) files of 3D models for porous chitosan composite were created using computeraided design (CAD) and printed with a hydrogel flow rate within the range of 0.2-0.25 ml/min. The prepared composite scaffolds were characterized by Fourier transform infrared spectroscopy (FTIR), X-Ray diffraction (XRD), scanning electron microscopy SEM, swelling property, mechanical testing, porosity, etc. In-vitro cell culture study was observed on 3D printed chitosan, gelatin, and alginate hydrogel scaffolds. The prepared scaffolds were highly porous, having optimum porosity, optimal mechanical strength to sustain the cartilage formation. The 3D printed chitosan composite scaffolds supported the differentiation of chondrocytes. The above study is helpful for in-vivo regeneration of cartilage for patients having related cartilage disorders.Abnormality behavior of the tumor is risky for human survival. Thus, finding cancer at the initial stage is beneficial for the reduction of mortality rate. Although it is not easy due to various factors concern with modalities, such as complex background, poor contrast, brightness issues, ill-defined borders, and shape of the infected area. Recently computer-aided systems (CAD) accomplish accurate diagnoses using different parts of the human body especially tumors detection in breast, brain, lung, liver, skin and colon cancer. Ponatinib clinical trial These human organs are evaluated using several diagnostic procedures, for instance, computed tomography (CT), magnetic resonance imaging (MRI), colonoscopy, mammography, dermoscopy and histopathology etc. The main intention of this research work is to investigate existing approaches for breast, brain, lung, liver, skin and finding of colon tumor. The study is conducted in terms of decision-making systems including handcrafted features and deep learning architectures employed for tumor detection.

Birt-Hogg-Dubé Syndrome (BHDS), an autosomal dominant hereditary condition, occurs due to mutations in the gene encoding folliculin (FLCN) in the short arm of the 17th chromosome characterized by lung cysts with specific skin findings and renal cell carcinoma. Patients are usually present with complaints of dyspnea and chest pain due to pneumothorax, but also may be asymptomatic due to wide phenotypic heterogeneity. Herein, we report the imaging findings of a case 32-year-old male with BHDS without any symptom who diagnosed incidentally by computed tomography (CT) because of being organ donation.

In a 32-year-old male patient evaluated as a potential liver donor, CT was performed for preoperative preparation. The patient's medical history was unremarkable. In the CT examination, multiple air cysts of different sizes in the both lungs were observed and also, a 7-cm solid renal mass of the right kidney was observed in the dynamic examination. Due to the large number of lung cysts and the presence of solid rtected in the donor organ or other organs in the examination area during radiological imaging. Although most incidental lesions are benign, important clinical conditions can be rarely observed, as in our case. Familial and syndromic conditions should also be kept in mind in the presence of solid renal masses incidentally detected at a young age. To the best of our knowledge, this is the first reported case of BHDS in English literature who was diagnosed incidentally on computed tomography for being living liver donor.

In this study, we aimed to find the percentage of random pathologies and abdominopelvic region anomalies that are not related to trauma in pediatric patients.

An abdominal assessment of an injured child usually involves computed tomography imaging of the abdomen and pelvis (CTAP) to determine the presence and size of injuries. Imaging may accidentally reveal irrelevant findings.

Although the literature in adults has reviewed the frequency of discovering these random findings, few studies have been identified in the pediatric population.

Data on 142 (38 female, 104 male) patients who underwent CTAP during their trauma evaluation between January 2019 and January 2020 were obtained from our level 3 pediatric trauma center records. The records and CTAP images were examined retrospectively for extra traumatic pathologies and anomalies.

67 patients (47%) had 81 incidental findings. There were 17 clinically significant random findings. No potential tumors were found in this population.

Pediatric trauma CTAP reveals random findings. For further evaluation, incidental findings should be indicated in the discharge summaries.

In this aim, we have developed this work to recommend an original route for the preparation of triazole derivatives.

Carbohydrates containing 1,2,3-triazole derivatives have various biological activities. Due to their advantageous and biological property, they are eye-catching synthetic targets in the arsenal of organic chemistry. Thus, finding green and efficient methods, as well as using ball millig procedure for the synthesis of these heterocycles is of interest to organic chemistry researchers.

The objective of this study was to synthesize carbohydrate-derived triazoles under high-speed vibration milling conditions and investigate their properties.

A mixture of glycoside azide derivatives (1 mmol) and prop-2-yn-1-ol (1.5 mmol) in the presence of copper (I) was vigorously shaken under vibration milling conditions at 650 rpm with three balls for 15 min. The deprotection of the resulting triazole derivatives was effected by treatment with 4M hydrochloric acid in methanol under reflux.

A short and convenient route to synthesize carbohydrate-derived triazoles, based in a ball-mill via 1,3-dipolar cycloaddition reactions to prop-2-yn-1-ol was developed.
