Purpose We determined the characteristics of Chinese men undergoing initial prostate biopsy and evaluated the relationship between prostate specific antigen levels and prostate cancer/high grade prostate cancer detection in a large Chinese multicenter cohort. Materials and Methods This retrospective study included 13,904 urology outpatients who had undergone biopsy for the indications of prostate

Full 3" wafer scale fabrication of porous silicon chips (pore chip protein arrays -PCPA) is reported. The PCPA is developed for the analysis of protein molecules based on the fluorescence and MALDI-TOF MS detection. The surface porosification process allows the creation of chips with different surface geometries to control the physical properties of the matrix in a highly reproducible way.

Inducible defences allow prey to increase survival chances when predators are present while avoiding unnecessary costs in their absence. Many studies report considerable inter-individual variation in inducible defence expression, yet what underlies this variation is poorly understood. A classic vertebrate example of a predator-induced morphological defence is the increased body depth in crucian ca

Importance Adverse pregnancy outcomes are recognized risk enhancers for cardiovascular disease, but the prevalence of subclinical coronary atherosclerosis after these conditions is unknown.Objective To assess associations between history of adverse pregnancy outcomes and coronary artery disease assessed by coronary computed tomography angiography screening.Design, Setting, and Participants Cross-s

BACKGROUND: X-ray micro-tomography (μCT) is a powerful non-destructive 3D imaging method applied in many scientific fields. In combination with propagation-based phase-contrast, the method is suitable for samples with low absorption contrast. Phase contrast tomography has become available in the lab with the ongoing development of micro-focused tube sources, but it requires sensitive and high-reso

Background: Brain metastases are associated with considerable negative effects on patients’ outcome in lung adenocarcinoma (LADC). Here, we investigated the proteomic landscape of primary LADCs and their corresponding brain metastases. Materials and methods: Proteomic profiling was conducted on 20 surgically resected primary and brain metastatic LADC samples via label-free shotgun proteomics. Afte

The derivation of dopamine neurons from human embryonic stem cells (hESCs) now offers a promising alternative to fetal tissue for cell replacement therapy (CRT) in Parkinson´s disease (PD). Using the appropriate chemical cues in vitro, hESCs can be patterned towards bona-fide ventral midbrain (VM) DA neurons that survive, reinnervate, release DA and provide functional recovery when transplanted in

BackgroundImmunosuppressed patients are particularly vulnerable to severe infection from the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), risking prolonged viremia and symptom duration. In this study we describe clinical and virological treatment outcomes in a heterogeneous group of patients with severe immunosuppression due to various causes suffering from COVID-19 infection, who

Background: Few MRA-based studies have systematically evaluated the prevalence and laterality of a fetal configuration of the posterior cerebral artery (FTP) in ischemic stroke populations versus other populations. This common variant is important in the setting of acute stroke and secondary prevention decisions. Objective: To determine the prevalence and laterality of FTP configurations in MRI-DW

BACKGROUND: We recently showed that striatal overexpression of brain derived neurotrophic factor (BDNF) by adeno-associated viral (AAV) vector exacerbated L-DOPA-induced dyskinesia (LID) in 6-OHDA-lesioned rats. An extensive sprouting of striatal serotonergic terminals accompanied this effect, accounting for the increased susceptibility to LID.OBJECTIVE: We set to investigate whether the BDNF effe

Purpose: Personalized cancer treatment requires predictive biomarkers, including image-based biomarkers. Breast cancer (BC) patients receiving neoadjuvant chemotherapy (NACT) are in a clinically vulnerable situation with the tumor present. This study investigated whether mammographic density (MD), assessed pre-NACT, is predictive of pathological complete response (pCR). Methods: A total of 495 BC

BACKGROUND: There is controversy about associations between total dietary fatty acids, their classes (saturated fatty acids [SFAs], monounsaturated fatty acids, and polyunsaturated fatty acids), and risk of coronary heart disease (CHD). Specifically, the relevance of food sources of SFAs to CHD associations is uncertain. METHODS AND RESULTS: We conducted a case-cohort study involving 10 529 incide

BACKGROUND: The identification of novel predictors of poor outcome may help stratify cardiovascular risk. Aim was to evaluate the individual contribution of blood cell count parameters, as well as their clustering, on the risk of death and cardiovascular events over the long term in the population-based Malmö Diet and Cancer Study cohort.METHODS: In 30,447 individuals (age 57 ± 8 years), we assess

BACKGROUND: With the increasing number of breast cancer (BC) diagnosed as a second primary malignancy after a first primary non-breast cancer (BCa-2), it is unclear about the familial risk of BC among women with a first-degree relative (FDR, parents or siblings) affected by a BCa-2.METHODS: In this Swedish nationwide cohort study, 5315 women with a FDR affected by BCa-2 and 115,048 women with a FD

Background: Prophylactic lightweight mesh in the sublay position reduced the cumulative incidence of parastomal hernia (PSH) after cystectomy with ileal conduit diversion in a randomised controlled trial.Objective: To investigate whether the use of prophylactic mesh is cost-effective in comparison to no mesh from the health care provider perspective.Design setting and participants: Data on health

PURPOSE: Exercise during chemotherapy has beneficial long-term effects on women with breast cancer, but short-term beneficial changes have been less investigated. Though short-term changes may be important as a encouraging factor, this study aimed to investigate immediate changes in self-reported energy, stress, nausea and pain following a single exercise session during chemotherapy.METHODS: Forty

Chronic inflammation is an HIV infection feature, contributing to elevated risk of cardiovascular disease among people with HIV, which can be induced by viral replication. A proportion of antiretroviral therapy (ART) recipients fail to achieve viral suppression, despite not meeting criteria for treatment failure, so-called low-level viremia (LLV). We investigated the relationship between LLV and a

We study resonant two-photon ionization of helium atoms via the 1s3p, 1s4p and 1s5p1P1 states using the 15th harmonic of a titanium-sapphire laser for the excitation and a weak fraction of the laser field for the ionization. The phase of the photoelectron wavepackets is measured by an attosecond interferometric technique, using the 17th harmonic. We perform experiments with angular resolution usin

Introduction: Cervical cancer is a major cause of mortality and morbidity. We aimed to estimate the association between sociodemographic factors and cervical neoplasia. Material and methods: In this Swedish nationwide open cohort study, 4 120 557 women aged ≥15 years at baseline were included between January 1, 2002 and December 31, 2018. The two outcomes were cervical cancer and carcinoma in situ
