Search for Daily Modulation of MeV Dark Matter Signals with DAMIC-M.

Dark matter (DM) particles with sufficiently large cross sections may scatter as they travel through Earth's bulk. The corresponding changes in the DM flux give rise to a characteristic daily modulation signal in detectors sensitive to DM-electron interactions. Here, we report results obtained from the first underground operation of the DAMIC-M prototype detector searching for such a signal from DM with MeV-scale mass.

First Constraints from DAMIC-M on Sub-GeV Dark-Matter Particles Interacting with Electrons.

We report constraints on sub-GeV dark matter particles interacting with electrons from the first underground operation of DAMIC-M detectors. The search is performed with an integrated exposure of 85.23 g days, and exploits the subelectron charge resolution and low level of dark current of DAMIC-M charge-coupled devices (CCDs).

Acute myocardium infarction: difficulties and interventions perceived by Italian nurses and physicians.

Background: Among cardiovascular diseases, acute coronary syndrome is the main cause of mortality and morbidity in the Western industrialized countries. Evidence suggested how continuous updating in cardiovascular area both for nurses and physicians was essential to improve patient outcomes in clinical process, welfare and rehabilitation, since physicians and nurses could play a key role in empowering the care of patients affected by the acute myocardium infarction (AMI). Although the correlation between continuous training and improvement of nursing care was therefore clear, the difficulties that nurses encountered in AMI patients' management remained unexplored.

Challenges in Diagnosis and Clinical Management of COVID-19 in Patient with B-Cell Chronic Lymphocytic Leukemia (CLL): Report of One Case.

We report here a case of a patient affected by B-cell chronic lymphocytic leukemia (CLL) that developed COVID-19 during the actual SARS-CoV-2 outbreak. The coexistence of CLL and COVID-19 raises many questions regarding the possible increased risk of developing COVID-19 among patients with CLL, the problems in managing therapies for both diseases and, above all, the difficulties in diagnosing COVID-19 in patients affected by CLL. In our patient, an 84-year-old man, the recognition of COVID-19 was delayed because of its atypical clinical presentation and technical problems related to the methods used for the diagnosis.

Detection of Pathological Markers of Neurodegenerative Diseases following Microfluidic Direct Conversion of Patient Fibroblasts into Neurons.

Neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease are clinically diagnosed using neuropsychological and cognitive tests, expensive neuroimaging-based approaches (MRI and PET) and invasive and time-consuming lumbar puncture for cerebrospinal fluid (CSF) sample collection to detect biomarkers. Thus, a rapid, simple and cost-effective approach to more easily access fluids and tissues is in great need. Here, we exploit the chemical direct reprogramming of patient skin fibroblasts into neurons (chemically induced neurons, ciNs) as a novel strategy for the rapid detection of different pathological markers of neurodegenerative diseases.

Psycho-cognitive assessment and quality of life in older adults with chronic obstructive pulmonary disease-carrying the rs4713916 gene polymorphism (G/A) of gene FKBP5 and response to pulmonary rehabilitation: a proof of concept study.

Purpose: Chronic obstructive pulmonary disease (COPD) is characterized by pulmonary and extra-pulmonary multi-morbidity including depression, anxiety and cognitive disorders. Several studies investigated the association of the FKBP5 gene polymorphisms with susceptibility to anxiety, depression, and behavioral disorders. The FKBP5 gene codifies the FKBP51 protein which modulates the glucocorticoid receptor in the adaptive stress response.

DNA repair protein DNA-PK protects PC12 cells from oxidative stress-induced apoptosis involving AKT phosphorylation.

Background: Emerging evidence suggest that DNA-PK complex plays a role in the cellular response to oxidative stress, in addition to its function of double strand break (DSB) repair. In this study we evaluated whether DNA-PK participates in oxidative stress response and whether this role is independent of its function in DNA repair.

Methods And Results: We used a model of HO-induced DNA damage in PC12 cells (rat pheochromocytoma), a well-known neuronal tumor cell line.

The role of nutraceutical medications in men with non bacterial chronic prostatitis and chronic pelvic pain syndrome: A prospective non blinded study utilizing flower pollen extracts versus bioflavonoids.

Introduction: Chronic prostatitis (CP)/chronic pelvic pain syndrome (CPPS) represents a challenge for the urologist, since the therapeutic efficacy does not always result in a satisfactory quality of life for the patients. Often the side effects of the medications used (antiinflammatories, antibiotics, alpha blockers) far outweighs the benefits gained with their admission. The choice of nutraceutical medications is preferred for their effectiveness, that has been accepted and proven by the scientific community, and for the low incidence of side effects.

Bacillus Calmette-Guérin unresponsiveness in non-muscle-invasive bladder cancer patients: what the urologists should know.

Transurethral resection of bladder (TURB) with adjuvant intravesical bacillus Calmette-Guérin (BCG) remains the gold standard therapy for intermediate- and high-risk non-muscle-invasive bladder cancer (NMIBC). However, this disease is burdened with a high risk of recurrence or progression. For this reason, we sought to review and summarize the current evidence with a non-systematic Medline/PubMed literature search, regarding optimal treatment in BCG failure patients.

Total phallic reconstruction after penile amputation for donkey bite: Case report and review of the literature.

There are very few reported cases of traumatic amputation of the male genitalia due to animal bite. The management involves thorough washout of the wounds, debridement, antibiotic prophylaxis, tetanus and rabies immunization followed by immediate reconstruction or primary wound closure with delayed reconstruction, when immediate reconstruction is not feasible. When immediate reconstruction is not feasible, long-term good functional and cosmetic results are still possible in the majority of cases by performing total phallic reconstruction.
