In lung inflammation, neutrophils are the first leukocytes migrating to an inflammatory site, eliminating pathogens by multiple mechanisms. The term "migration" describes several stages of neutrophil movement to reach the site of inflammation, of which the passage of the interstitium and basal membrane of the airway are necessary to reach the site of bronchial inflammation. Currently, several methods exist (e.g., Boyden Chamber, under-agarose assay, or microfluidic systems) to assess neutrophil mobility. However, these methods do not allow for parameterization on single cell level, that is, the individual neutrophil pathway analysis is still considered challenging...

The spleen selectively removes cells with intracellular inclusions, for example, detached nuclear fragments in circulating erythrocytes, called Howell-Jolly Bodies (HJBs). With absent or deficient splenic function HJBs appear in the peripheral blood and can be used as a simple and non-invasive risk-indicator for fulminant potentially life-threatening infection after spleenectomy. However, it is still under debate whether counting of the rare HJBs is a reliable measure of splenic function. Investigating HJBs in premature erythrocytes from patients during radioiodine therapy gives about 10 thousand times higher HJB counts than in blood smears...

BACKGROUND: Intranasal administration of benzodiazepines has shown superiority over rectal administration for terminating emergency epileptic seizures in human trials. No such clinical trials have been performed in dogs. OBJECTIVE: To evaluate the clinical efficacy of intranasal midazolam (IN-MDZ), via a mucosal atomization device, as a first-line management option for canine status epilepticus and compare it to rectal administration of diazepam (R-DZP) for controlling status epilepticus before intravenous access is available...

In 2015, a flourish of "alarums and excursions" by the scientific community propelled CRISPR/Cas9 and other new gene-editing techniques into public attention. At issue were two kinds of potential gene-editing experiments in humans: those making inheritable germ-line modifications and those designed to enhance human traits beyond what is necessary for health and healing. The scientific consensus seemed to be that while research to develop safe and effective human gene editing should continue, society's moral uncertainties about these two kinds of experiments needed to be better resolved before clinical trials of either type should be attempted...

For medical workers, ultrasound phantoms for human soft tissue are used not only for accuracy management of ultrasound diagnosis but also to aid ultrasound-guided needle and blind catheter insertion training without risk to real patients. For the phantoms, ultrasound characteristics and a texture are required to mimic the human soft tissue. The proposed phantom was composed of sodium alginate, calcium sulfate dihydrate, trisodium phosphate 12-hydrate, glycerol, and water. The propagation speed, attenuation coefficient, acoustic impedance, and texture of the proposed phantom were almost the same as those of human soft tissue...

BACKGROUND: High density lipoprotein (HDL) cholesterol is not decreased in hypercortisolism despite high triglycerides, which may be ascribed to effects on the cholesteryl ester transfer protein (CETP) pathway. We explored if CETP mRNA expression is modulated by glucocorticoid treatment in vitro. Effects of doubling the hydrocortisone (HCT) replacement dose on plasma CETP activity and HDL characteristics were tested in patients with secondary adrenal insufficiency. MATERIALS AND METHODS: Human THP-1 macrophages were incubated with corticosterone in vitro in the presence or absence of a liver X receptor (LXR) agonist, followed by determination of CETP mRNA levels by quantitative real-time PCR...

PROBLEM/CONDITION: Malaria in humans is caused by intraerythrocytic protozoa of the genus Plasmodium. These parasites are transmitted by the bite of an infective female Anopheles mosquito. The majority of malaria infections in the United States occur among persons who have traveled to regions with ongoing malaria transmission. However, malaria is occasionally acquired by persons who have not traveled out of the country through exposure to infected blood products, congenital transmission, laboratory exposure, or local mosquitoborne transmission...

Zhi Hao Jiang, Zheng Cui, Taiwei Yue, Yong Zhu, Douglas H Werner
A compact and flexible circularly polarized (CP) wearable antenna is introduced for wireless body-area network systems at the 2.4 GHz industrial, scientific, and medical (ISM) band, which is implemented by employing a low-loss composite of polydimethylsiloxane (PDMS) and silver nanowires (AgNWs). The circularly polarized radiation is enabled by placing a planar linearly polarized loop monopole above a finite anisotropic artificial ground plane. By truncating the anisotropic artificial ground plane to contain only 2 by 2 unit cells, an integrated antenna with a compact form factor of 0...

BACKGROUND AND AIM: Erectile dysfunction (ED) is the inability or insufficiensy of penile erection that causes dissatisfaction during sexual intercourse. ED is seen in patients with heart failure (HF) ranging from %56-81 depending on the severity. Patients usually blame their cardiovascular medications for their ED. Ivabradine is used for antianginal effects and to improve exercise intolerance and decrease mortality in patients with HF. Most beta-blockers are known to cause ED but unlike beta-blockers the effect of ivabradine over ED has never been evaluated...

Stigma and mental health literacy affect access to and quality of treatment of major depression. Though mental health professionals seem better able to recognize major depression than the general public, they often hold similarly stigmatizing attitudes towards people suffering from the disorder. These attitudes are shaped jointly by the public stigma attached to mental illnesses as well as by the content and delivery of mental health professionals' undergraduate training. In line with this, the present study aimed to explore psychology students' ability to recognize major depression, their attitudes towards the disorder, and their views surrounding helpfulness of various interventions...

The reform and development of psychiatric services require, in addition to financial resources, reserves in specialized human resources. The role of psychiatrists in this process, and at reducing the consequences of mental morbidity is evident. Psychiatrists are required to play a multifaceted role as clinicians, as experts in multidisciplinary team environments and as advisors in the recognition of public needs in mental health issues, as teachers and mentors for students and other health professionals, as researchers in order to enrich our knowledge in the scientific field of psychiatry, and as public health specialists in the development of the mental health services system...

Needle insertion being the most basic skill in medical care, training has to be imparted not only for physicians but also for nurses and paramedics. In most needle insertion procedures haptic feedback from the needle is the main stimulus that novices are to be trained in. For better patient safety, the classical methods of training the haptic skills have to be replaced with simulators based on new robotic and graphics technologies. This paper reviews the current advances in needle insertion modeling. It is classified into three sections: needle insertion models, tissue deformation models, and needle-tissue interaction models...

Hyperkalemia is an important complication of adrenalectomy for patients with primary aldosteronism (PA). The frequency of hyperkalemia after medication using mineralocorticoid receptor antagonists (MRAs) for PA is unclear. The aim of this study is to investigate the frequency and the risk factors of hyperkalemia after surgery and medication for PA. The data of 376 patients with PA registered in a multicentre-collaborative study in Japan, including surgically treated patients (group A; n=142) and medically treated patients with MRAs (group B; n=234) were studied...

We report the case of a 54 years old patient monitored for a monoclonal IgG kappa light chain refractory relapsed multiple myeloma and receiving daratumumab immunotherapy. Daratumumab (DARA), a monoclonal anti-CD38 antibody, belongs to the new generation of immunotherapy in refractory relapse multiple myeloma which the medical pathologist should be aware of to avoid misinterpretation of biological tests performed for patients followed for this disease. By its IgG1K humanized monoclonal antibody backbone, DARA interferes in both serum protein electrophoresis and immunofixation by the presence of an alternate IgGK monoclonal peak, leading to a possible difficulty to assess treatment's response in monoclonal IgG kappa light chain myeloma...

REVIEW
Tanja Varl, Damjan Grenc, Rok Kostanjšek, Miran Brvar
In Central Europe, reports of human envenomation by Cheiracanthium punctorium, commonly known as the yellow sac spider, are sporadic, despite the fact that this species is widespread in Europe. However, in recent years, C. punctorium has been repeatedly described globally in medical and toxicological literature. Its venom was found to possess insecticidal, haemolytic, cytotoxic, and membrane-damaging activities. Its bite is often very painful, frequently associated with local and transient cutaneous and neurotoxic effects, but sometimes also with systemic symptoms which require medical help...
