Amyotrophic lateral sclerosis is a progressive and fatal neurodegenerative disease characterized by the degeneration of motor neurons, which are the central nervous system cells that control voluntary muscle movements. The excessive salivation (sialorrhea) is present in approximately 50% of amyotrophic lateral sclerosis cases. Thus, some alternative therapeutic methods are sought, such as anticholinergic drugs and surgery. Recently the use of botulinum toxin applied at a midpoint of the salivary glands, often guided by ultrasound, have demonstrated positive results...

The normal histology of anogenital mammary-like glands (AGMLG) has been studied previously, but some aspects, including glandular depth, presence of columnar epithelium resembling columnar cell change/hyperplasia as defined in mammary pathology, and distribution of elastic fibers, have not been previously investigated. To address these issues, we studied 148 AGMLG identified in 133 paraffin blocks sampled from 64 vulvar wide excision or vulvectomy specimens (64 patients, various indications for surgery). The depth of AGMLG ranged from 0...

BACKGROUND: Sialodochitis fibrinosa is a rare disease which is characterized by recurring episodes of pain and swelling of the salivary glands due to the formation of mucofibrinous plugs. Analytic studies ascertain elevated levels of eosinophils and immunoglobulin E (IgE). Imaging studies such as magnetic resonance imaging (MRI) and sialography reveal dilation of the main salivary duct (duct ectasia). Treatment is initially supportive, consisting of compressive massages, and use of antihistamines and/or corticosteroids...

BACKGROUND: Autoimmune polyglandular syndrome type 2 (APS-2), also known as Schmidt's syndrome, is an uncommon disorder characterized by the coexistence of Addison's disease with thyroid autoimmune disease and/or type 1 diabetes mellitus. Addison's disease as the obligatory component is potentially life-threatening. Unfortunately, the delayed diagnosis of Addison's disease is common owing to its rarity and the nonspecific clinical manifestation. METHODS: Here we reported a case of 38-year-old female patient who presented with 2 years' history of Hashimoto's thyroiditis and received levothyroxine replacement...

: Abstracts Background: Implantation failure of in vitro fertilization (IVF) cycles is recognized as one of key problems in contemporary reproductive medicine. Implantation itself is a multifactorial process and one can hardly expect to find a single criterion for the endometrium receptivity. Endometrium biopsy still remains the most applicable technique to diagnose abnormalities causing decrease or complete loss of endometrial receptivity. MATERIALS AND METHODS: We have studied 95 endometrial biopsy samples from 45 patient with I/II stage endometriosis and 40 controls from October 2014 to December 2015...

The objective of this report was to identify potential factors associated with recurrent sialolithiasis after surgical intervention. This is a report of a woman with recurrent submandibular sialolithiasis after surgical intervention. Several characteristics of this patient indicate that she may have been predisposed to recurrent stone formation. Patient and disease factors leading to recurrent salivary stone formation are not well known. Notwithstanding, there may be stone factors and intraoperative findings that aid in determining whether a patient is likely to be successfully treated with a gland-sparing approach...

Wearable sweat biosensensing technology has dominantly relied on techniques which place planar-sensors or fluid-capture materials directly onto the skin surface. This 'on-skin' approach can result in sample volumes in the μL regime, due to the roughness of skin and/or due to the presence of hair. Not only does this increase the required sampling time to 10's of minutes or more, but it also increases the time that sweat spends on skin and therefore increases the amount of analyte contamination coming from the skin surface...

BACKGROUND: Perchlorate salts are relatively stable, soluble in water, and migrate into groundwater sources. Groundwater is an essential source for drinking water suppliers. Perchlorate bears health risks as it is identified to impair normal thyroid function by interfering with iodine uptake by the thyroid gland. The development of a sensitive analytical method for the determination of perchlorate is therefore of the highest interest or public health. Ion chromatography is a sensitive method suitable for perchlorate determinations...

Antimicrobial peptides (AMPs) are a wide-ranging class of host-defense molecules that act early to contest against microbial invasion and challenge. These are small cationic peptides that play an important in the development of innate immunity. In the oral cavity, the AMPs are produced by the salivary glands and the oral epithelium and serve defensive purposes. The aim of this review was to discuss the types and functions of oral AMPs and their role in combating microorganisms and infections in the oral cavity...

Cell growth and differentiation are often driven by subtle changes in gene expression. Many challenges still exist in detecting these changes, particularly in the context of a complex, developing tissue. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) allows relatively high-throughput evaluation of multiple genes and developmental time points. Proper quantification of gene expression levels by qRT-PCR requires normalization to one or more reference genes. Traditionally, these genes have been selected based on their presumed "housekeeping" function, with the implicit assumption that they are stably expressed over the entire experimental set...

Our previous studies showed that adenosine 5'-monophosphate-activated protein kinase (AMPK)/the target of rapamycin (TOR) signaling is involved in prothoracicotropic hormone (PTTH)-stimulated ecdysteroidogenesis in Bombyx mori prothoracic glands (PGs). In the present study, we further investigated the signaling involved in PTTH-stimulated phosphorylation of 4E-BP. We found that 4E-BP phosphorylation stimulated by PTTH was partially reduced in Ca(2+)-free medium, indicating the involvement of Ca(2+). In addition, we found that a potent and specific inhibitor of phospholipase C (PLC), U73122, greatly inhibited 4E-BP phosphorylation...

Most parotid tumors grow slowly, and sometimes these patients do not request surgical treatment until the tumors become large and affect their appearance. The surgical treatment of these large tumors is usually accompanied by large skin defects after excision, and it is challenging for surgeons to close the defect primarily. This report describes the case of a 68-year-old man with a left parotid gland tumor (largest dimension, 110 mm) and the case of a 79-year-old man with a left parotid gland tumor measuring approximately 77 mm that had existed for decades...
