J Feito, J L Cobo, A Santos-Briz, J A Vega
The occurrence of Pacinian corpuscles associated to lymph nodes is an anatomical rarity and very scarce information exists in this regard. Here we examined immunohistochemically four Pacinian corpuscles found in the close vicinity of the hiliar blood vessels of lymph nodes (2 cervical, 1 axillary, and 1 inguinal) during routine surgical pathology. Pacinian corpuscles were normally arranged and displayed a pattern of protein distribution as follows: the axon was positive for neurofilament proteins and neuron specific enolase, the inner core cells showed intense S100 protein and vimentin immunostaining while they were negative for glial fibrillary acidic protein, type IV collagen and glucose transporter 1; vimentin, type IV collagen, and glucose transporter 1 were also observed also in the outer-core and the capsule...

The two chromosomal copies of the human genome are highly polymorphic, and the allelic content on each strand can dictate a person's biological outcomes. While many of the current diagnostic tools are able to detect the presence of multiple mutations at the same time, most cannot determine the phase of these mutations unless long-range PCR or sequencing techniques are used or if templates are compartmentalized into single copies prior to amplification. Here, an enzyme-coupled hybridization assay, named Conditional Displacement Hybridization Assay (CDHA), is described for the concurrent and rapid determination of the presence and phase of SNP variants...

While the epidermal growth factor receptor (EGFR) is an established regulator of skin development and homeostasis, the functions of the related tyrosine kinase receptors ERBB2 and ERBB3 in this tissue have only recently been examined. Previously reported, skin-specific deletion of each of these receptors in mice resulted in similar defects in keratinocyte proliferation and migration, resulting in impaired wound healing and tumorigenesis. Because both ERBB2 and ERBB3 are targets for treating an array of cancer types, it is important to examine the consequences of receptor inhibition in human keratinocytes...

Objective measurements of melanin can provide important information for differentiating melanoma from benign pigmented lesions and in assessing pigmentary diseases. Herein, we evaluate near infrared fluorescence as a possible tool to quantify melanin. Various concentrations of in vitro Sepia melanin in tissue phantoms were measured with near-infrared fluorescence and diffuse reflectance spectroscopy. Similar optic measurements were conducted in vivo on 161 normal human skin sites. Diffuse reflectance spectroscopy was used to quantify the melanin content via Stamatas-Kollias algorithm...

Telmisartan, an angiotensin receptor blocker (ARB), is indicated for the treatment of essential hypertension. This study aimed to develop a mechanistic model of telmisartan drug effect in human using non-invasive markers. Data were acquired from a previous study where telmisartan 80 mg was given once daily for 6 days. Systolic (SBP) and diastolic blood pressure (DBP) and heart rate (HR) were measured before dosing for day 1 to 5 and serially after the last dose. Mean arterial pressure (MAP) and pulse pressure (PP) were calculated from SBP and DBP...

OBJECTIVES: Stress urinary incontinence (SUI) diminishes the quality of life of millions, particularly women who have delivered vaginally, which can injure the urethral sphincter. Despite several well-established treatments for SUI, growth factor therapy might provide an alternative to promote urethral sphincter repair. The goal of this study was to determine the effects of controlled release of IGF1 from alginate-poly-L-ornithine-gelatin microbeads (IGF1-A-PLO-G microbeads) on sphincter tissue regeneration in a rat model of SUI...

Human heparanase (HPSE) is an enzyme that degrades the extracellular matrix. It is implicated in a multiplicity of physiological and pathological processes encouraging angiogenesis and tumor metastasis. The protein is a heterodimer composed from a subunit of 8 kDa and a subunit of 50 kDa. The two protein subunits are non-covalently associated. The cloning and expression of the two protein subunits in Escherichia coli, and their subsequent purification to homogeneity under native conditions result in the production of an active heparanase enzyme...

REVIEW
Elizabeth Rivers, Adrian J Thrasher
The Wiskott Aldrich syndrome protein (WASP) participates in innate and adaptive immunity through regulation of actin cytoskeleton-dependent cellular processes, including immune synapse formation, cell signaling, migration and cytokine release. There is also emerging evidence for a direct role in nuclear transcription programmes uncoupled from actin polymerization. A deeper understanding of some of the more complex features of Wiskott Aldrich syndrome (WAS) itself, such as the associated autoimmunity and inflammation, has come from identification of defects in the number and function of anti-inflammatory myeloid cells and regulatory T and B cells, as well as defects in positive and negative B-cell selection...

Cecilia Coale Van Hollen
Medical practitioners, bioethicists, psychologists, and anthropologists have debated whether it is ethical to disclose or withhold information from patients about cancer diagnoses. This debate is framed as pitting universal individual human rights against cultural pluralism. The rights-based argument asserts that people have a right to information about their own health to make the best decisions about their treatment. The cultural variation argument suggests that in some cultural contexts there is a perception that information about one's cancer diagnosis may cause more harm than good due to the psychological trauma this may cause...

Increasing the utilisation of plant proteins is needed to support the production of protein-rich foods that could replace animal proteins in the human diet so as to reduce the strain that intensive animal husbandry poses to the environment. Lupins, quinoa and hempseed are significant sources of energy, high quality proteins, fibre, vitamins and minerals. In addition, they contain compounds such as polyphenols and bioactive peptides that can increase the nutritional value of these plants. From the nutritional standpoint, the right combination of plant proteins can supply sufficient amounts of essential amino acids for human requirements...

A 56-year-old epileptic patient underwent right hemicolectomy and cholecystectomy surgery under general endotracheal anesthesia. Anesthesia was maintained with sevoflurane, and sufentanil, rocuronium, and dexmedetomidine infusions. After the operation and confirmation of neuromuscular recovery, the patient woke from anesthesia within 15 min and successfully extubated. After the vital signs of patient were stable, the patient was transported to post anesthesia care unit (PACU). 6 h after the surgery, he fell into a stuporous state for lasting 14 h and EEG showed no epileptiform discharges...

HIV testing services are the gateway into HIV treatment and are critical for monitoring the epidemic. HIV testing is recommended at least annually in high-risk populations, including people who inject drugs (PWID). In Malaysia, the HIV epidemic is concentrated among PWID, but their adherence to testing recommendations and the proportion of HIV-positive PWID who are aware of their status remain unknown. We recruited 460 PWID in Greater Kuala Lumpur using respondent-driven sampling and conducted HIV testing. We examined past testing behaviors, estimating testing frequency, correlates of testing in the past 12 months, and the proportion of those living with HIV who were aware of their status...

PURPOSE: The superior soft tissue contrast of magnetic resonance imaging (MRI) compared to computed tomography (CT) has urged the integration of MRI and elimination of CT in radiotherapy treatment (RT) for prostate. An intraprostatic gold fiducial marker (GFM) appear hyperintense on CT. On T2 weighted (T2w) MRI target delineation images the GFM appear as a small signal void similar to calcifications and post biopsy fibrosis. It can therefore be difficult to identify the markers without CT...

Solasodine is a main active component isolated from Solanum incanum L, who performs a wide range of functions containing anti-oxidant, anti-infection and neurogenesis promotion. In this study, we explored the influence of solasodine on three types of human colorectal cancer (CRC) cell lines. The consequences displayed that solasodine apparently prohibited CRC cell proliferation dose- and time-dependently and impeded CRC cell motility by downregulating Matrix metalloprotease (MMPs). Besides, solasodine was investigated to fuel caspase-cascade reaction and increase the ratio between Bax and Bcl-2 so as to induce CRC cell apoptosis...

Humans exhibit population level handedness for the right hand; however, the evolution of this behavioral phenotype is poorly understood. Here, we compared the laterality of a simple task (grooming) and a complex task (tool use) to investigate whether increasing task difficulty elicited individual hand preference among a group of captive bonobos (Pan paniscus). Subjects were 17 bonobos housed at the Columbus Zoo and Aquarium. Laterality of grooming was recorded using group scans; tool use was recorded using all-occurrence sampling...

Alcohol use disorders, affective disorders and their comorbidity are sexually dimorphic in humans. However, it is difficult to disentangle the interactions between subject factors influencing alcohol sensitivity in studies of humans. Herein, we combined murine models of unpredictable, chronic, mild stress (UCMS) and voluntary binge-drinking to examine for sex differences in the interactions between prior histories of excessive ethanol-drinking and stress upon ethanol-induced changes in motor behavior and subsequent drinking...
