We propose that a similar structural diversity is of relevance to many other CaM complexes.On 15 October, 2020, Dr. Paul M. Weinberg, a true giant in the field of paediatric cardiology, succumbed to a prolonged illness. Dr. Weinberg had a 43-year career and was described as a pillar of The Children's Hospital of Philadelphia and the spirit of the Division of Cardiology, a cherished and beloved teacher, and an outstanding clinician. His impact on the field and on the careers of his students will be remembered for generations to come.In 2019, Dr. Weinberg wrote for Jefferson Medical School's 50th year reunion memory book "In the true spirit of Hippocrates, I seek to mentor the next generation as I was mentored by the last, without expectation of reward. I am forever indebted to these educators for all the knowledge they imparted to me and for the wisdom that I acquired under their tutelage." These words are a true reflection of his unassuming dedication to teaching the next generation of paediatric cardiologists. His legacy will continue to live on through these trainees and impact the field for generations to come.
The administration of improperly prepared intravenous fluids might determine healthcare-associated infections. Quality and sterility assurance in radiopharmaceutical manufacturing products must be evaluated by media fill tests that simulate the performance of the aseptic manufacturing procedure. The aim of this study is to show a methodological modification of a specific step of media fill tests, giving an overview of economic and organizational advantages that it might bring.

Media fill tests were conducted to ensure that they reproduce as strictly as possible the routine aseptic production process with all the critical steps described in the internal Standard Operating Procedures. We introduced an innovative modification in step 1 instead of using a completely decayed
Mo/
Tc generator, we used a
Mo/
Tc generator just before its disposal, eluting it with saline solution aspirated in an empty vacuum vial.

A total of 47 production runs were performed, and a total of 799 vials were tested for sterility. Thirteen nuclear medicine technicians were assessed. We found contamination in 1% of the total number of vials analyzed.

The modification proposed shows several advantages reduction of the costs of the media fill tests, the possibility to manage these without referring to external services, and decreased injuries for technicians who perform the tests.

Diabetic peripheral neuropathy (DPN) is the major form of neuropathy found in 75% of diabetic neuropathy incidences. read more Pharmacological treatments are recommended for pain management in DPN. link2 Anticonvulsants like pregabalin and gabapentin are the preferred first-line treatment, followed by amitriptyline, duloxetine, and venlafaxine. Topical agents like capsaicin and isosorbide dinitrate are also useful in treating the DPN and may be considered for the second or third-line treatment. Opioids and related drugs are suggested for short-term use during the acute exacerbation of pain. Combination therapy may be beneficial in patients who do not respond to monotherapy. However, currently, there is no compelling evidence to suggest any specific combination of agents. Disease-modifying agents such as alpha-lipoic acid and epalrestat appear to improve the disease state but are not recommended by any guideline. This review discusses the available pharmacological therapy for treating DPN. Also, we highlight the recommendations from different guidelines about the pharmacological treatment of DPN.
The conifer species Pinus halepensis (Pinaceae) and Tetraclinis articulata (Cupressaceae) are widely used in traditional medicine due to their beneficial health properties.

This study aimed to investigate the mechanisms by which P. halepensis and T. articulata essential oils (1% and 3%) could exhibit neuroprotective effects in an Alzheimer's disease (AD) rat model, induced by intracerebroventricular (i.c.v.) administration of amyloid beta1-42 (Aβ1-42).

The essential oils were administered by inhalation to the AD rat model, once daily, for 21 days. DNA fragmentation was assessed through a Cell Death Detection ELISA kit. Brainderived neurotrophic factor (BDNF), activity-regulated cytoskeleton-associated protein (ARC), and interleukin-1β (IL-1β) gene expressions were determined by RT-qPCR analysis, while BDNF and ARC protein expressions were assessed using immunohistochemistry technique.

Our data showed that both essential oils substantially attenuated memory impairments, with P. halepensis mainly stimuld their chemical constituents could be natural agents of therapeutic interest against Aβ1-42-induced neurotoxicity.Due to the lack of vascular distribution and the slow metabolism, cartilage tissue cannot repair itself, which remains a huge challenge in cartilage regeneration. Tissue engineering using stem cells appears to be a promising method for cartilage repair. Tissue engineers demonstrated that mechanical stimulation can enhance the quality of engineered cartilage, making it more similar to natural cartilage in structure and function. In this review, we summarize recent studies on the role of mechanical stimuli in chondrogenesis, focusing on the applications of extrinsic mechanical loading and the studies on mechanical properties of biomaterials in cartilage tissue engineering. This review will provide fresh insights into the potential use of mechanical stimuli for clinical use.Mesenchymal stem cells (MSCs) have shown promising therapeutic effects in a wide variety of medical conditions, including neurodegenerative disorders and cardiovascular diseases. Although preliminary research has emphasized the ability of MSCs to engraft at sites of injury, several studies have revealed that MSCs mediate their effects through the release of various paracrine factors and through their antioxidant, anti-inflammatory, immunomodulatory, and anti-apoptotic effects. The clinical implications of MSCs application are limited due to their low survival rate in conditions of inflammation, oxidative stress, and nutrient restriction in damaged areas. Furthermore, the function of isolated MSCs is usually affected by the patient's health. Therefore, it is necessary to develop new methods to enhance the therapeutic efficacy of MSCs under pathophysiological conditions. This review provides an overview of the general properties of MSCs, their therapeutic potential in neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease, multiple sclerosis, amyotrophic lateral sclerosis, and Huntington's disease, as well as cardiovascular diseases such as myocardial infarction, diabetic cardiomyopathy, and dilated cardiomyopathy, and their related mechanisms. In addition, this review also discusses potential problems and side effects, as well as current and future directions for improvement of MSCs therapy and their implications and applications.Neurological diseases have different etiological causes. Contemporary, developing an effective treatment for these diseases is an ongoing challenge. Cell therapy is recognized as one of the promising solutions for the treatment of these diseases. Amongst various types of stem cells, bone marrow-derived mesenchymal stem cells (BM-MSC) are known to be the most widely used stem cells. These cells are endowed with appealing properties such as the ability to differentiate into other cell types, including the muscle, liver, glial, and nerve cells. In this review study, we have systematically evaluated the ability of a variety of chemical compounds used in the last ten years to differentiate BM-MSCs into neurons by examining the expression level of beta-tubulin 3 protein. The present study is a systematic search performed at three separate databases, including PubMed, ScienceDirect, and Embase from August 2009 to August 2019. The search results in the three mentioned databases were 323 articles and finally, 8 articles were selected and carefully examined considering the inclusion and exclusion criteria. The results showed that different chemical compounds such as ROCK inhibitors, sex steroid hormones, bFGF, NGF, Noggin, 4 OHT, TSA, VPA, Antidepressants, Neurosteroids (Dex and E2), and DHA are involved in different signaling pathways, such as ERK, AKT, BMP, DHA / GPR40, Rho-dependent phosphorylation, and histone deacetylase inhibitors. Further investigation of these signaling pathways may open the way for better differentiation of BM-MSCs into neurons.The use of a navigation system allows precise resection of a tumor and accurate reconstruction of the resultant defect thereby sparing important anatomical structures and preserving function. It is an "image-based" system where the imaging (computed tomography and magnetic resonance imaging) is required to supply the software with data. The fusion of the preoperative imaging provides pre-operative information about local anatomy and the extent of the tumor so that it allows accurate preoperative planning. Accurate pre-operative imaging is mandatory in order to minimize CATS errors, thus performing accurate tumor resections.
Peritumoral edema of primary brain tumors is an important cause of morbidity and mortality. The number of studies currently available on the prognostic role of peritumoral brain edema in the posterior fossa is extremely limited.

Based on the known importance of magnetic resonance imaging in diagnosing supratentorial metastases, this study aimed to investigate the effects of peritumoral edema on survival of patients with posterior fossa metastases and the preoperative diagnostic value of MRI.

Edema and mass volumes of 49 patients with posterior fossa metastasis, who underwent surgery during 2012-2016, were measured using magnetic resonance imaging. The edema/mass indices were retrospectively calculated and interpreted by evaluating the demographic, clinical, and survival data.

The study consisted of 32 (65.3%) male and 17 (34.7%) female participants, with the mean age ± standard deviation of 47.25±29.25 (17-81) years. Among the 49 patients with posterior fossa metastases, 34 (69.4%) had carcinoma, while 15 (30.6%) had non-carcinoma metastases. The edema/mass indices of patients with carcinoma and non-carcinoma metastases were found to be 14.55±9.64 and 1.34±1.08, respectively, and the difference was statistically significant (p<0.001). link3 The mean survival of patients with carcinoma and non-carcinoma metastases was found to be 642±11.52 days and 726±9.32 days, respectively; however, this difference was not statistically significant (p=0.787).

The edema/mass ratio was found to be a significant diagnostic factor for the prediction of posterior fossa metastases. Further detailed studies are warranted to investigate the effect of edema/mass ratio on survival rate.
