Project description:We present a comprehensive dataset of 5,323 images of mint (pudina) leaves in various conditions, including dried, fresh, and spoiled. The dataset is designed to facilitate research in the domain of condition analysis and machine learning applications for leaf quality assessment. Each category of the dataset contains a diverse range of images captured under controlled conditions, ensuring variations in lighting, background, and leaf orientation. The dataset also includes manual annotations for each image, which categorize them into the respective conditions. This dataset has the potential to be used to train and evaluate machine learning algorithms and computer vision models for accurate discernment of the condition of mint leaves. This could enable rapid quality assessment and decision-making in various industries, such as agriculture, food preservation, and pharmaceuticals. We invite researchers to explore innovative approaches to advance the field of leaf quality assessment and contribute to the development of reliable automated systems using our dataset and its associated annotations.
Project description:Endometriosis is a chronic disease, in which endometrial-like tissue is found outside the uterine cavity. Lesions are typically located in the true pelvis but can be found, in addition to extragenital endometriosis, in the respiratory system, the diaphragm, the pleura or the pericardium. As the extrauterine endometrial lesions undergo the menstrual cycle, they cause many symptoms, including pain, and besides infertility, they all mostly affect the quality of the patient's life. Pharmacological management of endometriosis significantly increases in importance either as a first-line treatment or as a complementary therapy after surgery. Yet, current research on antagonists of the gonadotropin-releasing hormone (GnRH) has revealed their potential benefits in endometriosis treatment. Their mechanism of action is to down-regulate the hypothalamic-pituitary-gonadal axis and therefore induce a hypoestrogenic state. The resulting reduction of estrogen levels prevents disease progression and diminishes the recurrence rate after surgical removal of endometriosis. The present review summarizes recent reports of the role oral GnRH antagonists have as a significant treatment option for pain reduction in endometriosis patients.
Project description:This narrative review aims to provide an overview of the current literature on the pharmacology, safety, efficacy and tolerability of intranasal esketamine, the S-enantiomer of ketamine, for the treatment of treatment-resistant depression (TRD). A literature search using Medline, Embase, PsycINFO and Cochrane Central was conducted (January 2000 to July 2019). Product information and www.clinicaltrials.gov were also reviewed. The literature search was limited to human studies published in English. Phase I, II, and III studies of intranasal esketamine for TRD were reviewed. About a third of patients with major depressive disorder fail to achieve remission despite treatment with multiple antidepressants. This article examines the trials that led to the approval of esketamine in the United States, as well as other recent studies of esketamine for TRD. The findings from limited phase III trials illustrate that intranasal esketamine is effective and safe in reducing depressive symptoms and achieving clinical response in patients with TRD. The optimum duration and frequency of use are not fully understood. Although the nasal spray is a convenient dosage form, its use in practice may be limited by cost and administrative regulation. While it may prove beneficial to many patients who suffer from TRD, further long-term data are required, along with comparative trials with the R-isomer (arketamine). In the interim, care and monitoring should be exercised in its use in clinical practice.
Project description:Clostridium difficile infection (CDI) is a potential life-threatening consequence of antibiotic therapy. Although the risk increases with duration of treatment, it can also occur after a short treatment course. In addition to broad-spectrum antibiotics, anti-neoplastic agents, proton pump inhibitors, H(2) blockers, and several other drugs have been reported to induce intestinal dysbiosis, which is central to the pathogenesis of CDI. There is an increase in incidence and mortality attributed to CDI globally. Moreover, the epidemiology of C. difficile-associated diseases has changed significantly with an increasing occurrence of community-acquired CDI. Metronidazole and oral vancomycin are the first-line antibiotics used to treat CDI. However, metronidazole has limited effectiveness in severe cases and vancomycin use is associated with increasing risk of vancomycin resistance among Enterococcus spp. Cadazolid, a novel oxazolidinone antibiotic, has recently shown potent antimicrobial activity against C. difficile and has a lower propensity to induce resistance. The implications of its use in treating CDI have been reviewed based on current evidence.
Project description:Acute myeloid leukemia (AML) treatment has always been a challenge to the treating physician. Continuous efforts are being made to improve treatment outcomes in AML. CPX-351 is a pharmacologic advancement in this direction. It is a liposomal fixed drug combination of cytarabine and daunorubicin. Early studies indicate that it will play a big role in AML treatment. This is a short review about this drug.
Project description:BackgroundIn the past decade, migraine research has identified novel drug targets. In this review, we discuss recent data on emerging anti-migraine therapies.Main bodyThe development of ditans, gepants and anti-calcitonin gene-related peptide monoclonal antibodies for the treatment of migraine is one of the greatest advances in the migraine field. Lasmiditan, rimegepant and ubrogepant will extend our therapeutic armamentarium for managing acute migraine attacks when triptans are not effective or contraindicated due to cardiovascular disorders. The monoclonal antibodies are migraine specific prophylactic drugs with high responder rates and favorable adverse event profiles. Furthermore, they offer convenient treatment regimens of 4- or 12-week intervals.ConclusionCollectively, novel migraine therapies represent a major progress in migraine treatment and will undoubtedly transform headache medicine.
Project description:Bachmann-Bupp syndrome (BABS) is a rare syndrome caused by gain-of-function variants in the C-terminus of ornithine decarboxylase (ODC coded by the ODC1 gene). BABS is characterized by developmental delay, macrocephaly, macrosomia, and an unusual pattern of non-congenital alopecia. Recent diagnosis of four more BABS patients provides further characterization of the phenotype of this syndrome including late-onset seizures in the oldest reported patient at 23 years of age, representing the first report for this phenotype in BABS. Neuroimaging abnormalities continue to be an inconsistent feature of the syndrome. This may be related to the yet unknown impact of ODC/polyamine dysregulation on the developing brain in this syndrome. Variants continue to cluster, providing support to a universal biochemical mechanism related to elevated ODC protein, enzyme activity, and abnormalities in polyamine levels. Recommendations for medical management can now be suggested as well as the potential for targeted molecular or metabolic testing when encountering this unique phenotype. The natural history of this syndrome will evolve with difluoromethylornithine (DFMO) therapy and raise new questions for further study and understanding.
Project description:Ventricular assist devices are commonly utilized in the treatment of end-stage heart failure. Advances in continuous flow technology have improved efficiency, size, implantability, extended support, and overall patient outcomes. This has led to an expanded role of left ventricular assist device (LVAD) clinical use and applications. This review describes the advances and current state of LVAD devices and provides a future outlook for this technology.
Project description:Inflammatory lung diseases represent a persistent burden for patients and the global healthcare system. The combination of high morbidity, (partially) high mortality and limited innovations in the last decades, have resulted in a great demand for new therapeutics. Are therapeutic IgA antibodies possibly a new hope in the treatment of inflammatory lung diseases? Current research increasingly unravels the elementary functions of IgA as protector against infections and as modulator of overwhelming inflammation. With a focus on IgA, this review describes the pathological alterations in mucosal immunity and how they contribute to chronic inflammation in the most common inflammatory lung diseases. The current knowledge of IgA functions in the circulation, and particularly in the respiratory mucosa, are summarized. The interplay between neutrophils and IgA seems to be key in control of inflammation. In addition, the hurdles and benefits of therapeutic IgA antibodies, as well as the currently known clinically used IgA preparations are described. The data highlighted here, together with upcoming research strategies aiming at circumventing the current pitfalls in IgA research may pave the way for this promising antibody class in the application of inflammatory lung diseases.
Project description:Obesity limits the access to kidney transplantation and increases the risk of complications and mortality posttransplantation. Usual noninvasive measures, including lifestyle changes and dietary education, do not provide long-term and consistent body weight reduction. In many cases, only bariatric surgery allows patients to significantly reduce body weight. We here report two cases of obese hemodialysis (HD) patients who were successfully treated with off-labeled semaglutide, a glucagon-like peptide receptor agonist (GLP-1RA). The first patient had a body mass index (BMI) of 45.7 kg/m2 despite a history of partial gastrectomy. The second patient had a history of type 2 diabetes mellitus and a BMI of 36.5 kg/m2. Both patients started semaglutide at the maximal subcutaneous dose of 1 mg/week, which was clinically well tolerated. During the 9-month follow-up, body weight loss ranged from 6.5 to 9.0 kg, ∼1 kg/month. GLP-1RAs, such as semaglutide or liraglutide, could be a novel pharmacological alternative to bariatric surgeries for these HD patients.
