Breast cancer has become a global problem. Though concerns regarding early detection and accurate diagnosis have been raised, continued efforts are required for the development of precision medicine. In the past years, the area of medicinal imaging has seen an unprecedented growth that has led to an advancement of radiomics, which provides countless quantitative biomarkers extracted from modern diagnostic images, including a detailed tumor characterization of breast malignancy.

In this review, we have presented the methodology and implementation of radiomics together with its future trends and challenges on the basis of published papers. Radiomics could distinguish malignant from benign tumors, predict prognostic factors, molecular subtypes of breast carcinoma, treatment response to neoadjuvant chemotherapy (NAC), and recurrence survival. The incorporation of quantitative knowledge with clinical, histopathological, and genomic information will enable physicians to afford customized care of treatment for patients with breast cancer.

This review was intended to help physicians and radiologists gain fundamental knowledge regarding radiomics, and also to work collaboratively with researchers to explore evidence for its further usage in clinical practice.

Avascular necrosis of humeral trochlea is a very rare condition and was described by Hegemann in 1957. We reported two cases of avascular necrosis of humeral trochlea and also performed a literature review of the reported cases. We expect that this case report will assist clinicians in making a timely diagnosis when encountering similar clinical scenarios.

We presented cases of an 11-year-old and a 14-year-old with avascular necrosis of the humeral trochlea. The common etiology was idiopathic because there were no recent trauma history and sports activity. Also, there was no history of drug use. We discussed the clinical and radiological findings of these cases.

These cases, two teenage boys, were diagnosed withHegemann's disease with clinical and radiological outcomes. We found that the etiology of both thecases is idiopathic;. The number of previously reported cases in the literature is limited to 64. In our study, there was a lateral crest in one of our two cases and a posteromedial involvement in another. The radiograph of trochleae of these two cases showed irregularity and granular appearance. In our case, heterogeneous signal changed and irregularities were accompanied by hypointensive changes on T1-weighted images. Also, hyperintensive changes on proton density sequences were detected.

Radiological evaluation plays an important role in the diagnosis and evaluation of response to treatment in avascular necrosis of the humeral trochlea. check details Avascular necrosis should be one of the differential lesions involving the trochlea. Recognition of avascular necrosis in the trochlea may prevent the unnecessary biopsy.

Few studies have evaluated the early use of insulin glargine in the management of diabetic ketoacidosis (DKA) patients. Early insulin glargine use in DKA was safe and associated with a trend towards faster DKA resolution.

To evaluate the efficacy and safety of early insulin glargine administration for acute management of DKA in critically ill patients.

This single-center retrospective cohort study included patients, who were >18 years of age with DKA, admitted to the intensive care unit (ICU) for at least 12 h, and received intravenous insulin infusion for at least 6 h. The primary endpoint was the association between the time to insulin glargine administration and time to DKA resolution. Linear and logistic regression analyses were performed.

Of the 913 patients evaluated, 380 were included in the study. The overall mean age was 45±17 years, 196 (51.6%) were female, and 262 (70%) patients had type 1 diabetes mellitus. The mean blood glucose level was 584.9±210 mg/dL, pH was 7.16±0.17, anion gap was 28.17±6.9 mEq/L, and serum bicarbonate level was 11.19±5.72 mEq/L. Every 6-h delay in insulin glargine administration was associated with a 26-min increase in time to DKA resolution (95% confidence interval [CI], 14.76-37.44; p<0.0001), 3.2-h increase in insulin infusion duration (95% CI, 28.8-36; p<0.0001), and 6.5-h increase in ICU LOS (95% CI, 5.04-7.92; p<0.0001).

Early administration of insulin glargine is potentially safe and may be associated with a reduction in time to DKA resolution and a shorter duration of insulin infusion.

Finally, we will try to explain the reasons that may justify the difficulty in translating good results in experimental studies to the usual clinical practice. This "good results" may be too little to be detected or there may be other causes but misinterpreted as effects of DHA.Organoselenium chemistry has undergone extensive development during the past decades, mostly due to the unique chemical properties of organoselenium compounds that have been widely explored in a number of synthetic transformations, as well as due to the interesting biological properties of these compounds. Diselenides and selenocyanates constitute the promising classes of organoselenium compounds that possess interesting biological effects, and that can be used in the preparation of other selenium compounds. The combination of diselenide and selenocyanate moieties with other biologically relevant molecules (such as heterocycles, steroids, etc.) is a way for the development of compounds with promising pharmaceutical potential. Therefore, the aim of this review is to highlight the recent achievements in the use of diselenides or selenocyanates as precursors for the synthesis of pharmaceutically relevant compounds, preferentially compounds with antitumor and antimicrobial activities.
Paclitaxel, a natural diterpenoid compound, has anti-tumor effect by acting on tubulin, whereas coumarin, another kind of natural product, has anti-tumor effect, along with some other effects, such as anti-bacterial-., Moreover, it also possesses fluorescence.

Multi targeting is an effective strategy in drug design to combat tumor. Therefore, a combination of paclitaxel with other active molecular drugs for exploring the novel lead with multi-functions is in demand.

To synthsize paclitaxel-coumarin conjugate via click chemistry and to investigate anticancer activity by MTT assay and the scratch test.

The results of MTT assay showed that compared tothe paclitaxel, the anti-tumor activity of the conjugate was significantly improved. The results of flow cytometry showed that the conjugate had a stronger ability to induce apoptosis. The scratch test results showed that the conjugate had better anti- metastasis ability than paclitaxel.

These findings indicated that paclitaxel and coumarin had a synergistic effect, which paved the way for the development of paclitaxel through fluorescence.

An inconsistent association between exposure to SSRIs and SNRIs and the risk for ASD and ADHD in the Offspring was observed in observational studies. Some suggest that the reported association might be due to unmeasured confounding. We aimed to study this association and to look for sources of bias by performing a systematic review and meta-analysis.

Medline, Embase, and the Cochrane Library were searched up to June 2019 for studies reporting on ASD and ADHD in the Offspring following exposure during pregnancy. We followed the PRISMA 2009 guidelines for data selection and extraction. Outcomes were pooled using random- effects models and odds ratios (OR), and 95% confidence intervals (CI) were calculated for each outcome using the adjusted point estimate of each study.

Eighteen studies were included in the meta-analysis. We found an association between SSRIs/ SNRIs prenatal use and the risk for ASD and ADHD (OR=1.42, 95% CI 1.23-1.65, I
=58%; OR=1.26, 95% CI 1.07-1.49, I2=48%, respectively). Similar fine of potential unmeasured confounding in the estimation of the association and perform a network meta-analysis.Adolescence is the transitional period between childhood and adulthood and a critical period in brain development. Adolescence in humans is also associated with increased expression of risk-taking behaviors. Epidemiological and clinical studies, for example, show a surge of drug abuse and raise the hypothesis that the adolescent brain undergoes critical changes resulting in diminished control. Determining how substance abuse during this critical period might cause longterm neurobiological changes in cognition and behavior is therefore critically important. The present work aims to provide an evaluation of the transgenerational and multi-generational phenotypes derived from parent animals exposed to drugs of abuse only during their adolescence. Specifically, we will consider changes found following the administration of cannabinoids, nicotine, alcohol and opiates. In addition, epigenetic modifications of the genome following drug exposure will be discussed as emerging evidence of the underlying adverse transgenerational effects. Notwithstanding, much of the new data discussed here is from animal models, indicating that future clinical studies are much needed to better understand the neurobiological consequences and mechanisms of drug actions on the human brains' development and maturation.MicroRNAs (miRNAs) are short ~18-22 nucleotide, single-stranded, non-coding RNA molecules playing a crucial role in regulating diverse biological processes and are frequently dysregulated during disease pathogenesis. Thus, targeting miRNA could be a potential candidate for therapeutic invention. This systemic review aims to summarize our current understanding regarding the role of miRNAs associated with Th2-mediated immune disorders and strategies for therapeutic drug development and current clinical trials.Undoubtedly, antibiotics have saved billions of lives, but lack of novel antibiotics, development of resistance mechanisms in almost all clinical isolates of bacteria, and recurrent infections caused by persistent bacteria hamper the successful treatment of the infections. Due to the widespread emergence of resistance, even the new families of anti-microbial agents have a short life expectancy. Drugs acting on a single target often lead to drug resistance and are associated with various side effects. For overcoming this problem, either multidrug therapy, or a single drug acting on multiple targets may be used. The latter is called 'hybrid molecules,' which are formed by clubbing two biologically active pharmacophores together, with or without an appropriate linker. In this rapidly evolving era, the development of natural product-based hybrid molecules may be a super-alternative to multidrug therapy, for combating drug resistance caused by various bacterial and fungal strains. Coumarins (benzopyran-2-one) are one of the earliest reported plant secondary metabolites having a clinically proven diverse range of pharmacological properties.
