The protease degradome is defined as the complete repertoire of proteases and inhibitors, and their nonfunctional homologs present in a cell, tissues or organism at any given time. We review the tissue distribution of virtually the entire degradome in 23 different human tissues and 6 ovarian cancer cell lines. To do so, we developed the CLIP-CHIP™, a custom microarray based on a 70-mer oligonucleotide platform, to specifically profile the transcripts of the entire repertoire of 473 active human proteases, 156 protease inhibitors and 92 non-proteolytically active homologs known at the design date using one specific oligonucleotide per transcript...

Directed evolution is a powerful tool to improve the characteristics of biomolecules. Here we present a protocol for the intracellular evolution of proteins with distinct differences and advantages in comparison with established techniques. These include the ability to select for a particular function from a library of protein variants inside cells, minimizing undesired coevolution and propagation of nonfunctional library members, as well as allowing positive and negative selection logics using basally active promoters...

Background: Adrenal incidentaloma refers to the incidental finding of a tumor in the adrenal gland, where nonfunctional forms are the most common variant. Myelolipoma is a rare (0.08-0.4%) occurrence characterized by adipose and hematopoietic tissue. The aim of this case report is to describe the diagnosis and appropriate management of a myelolipoma in an asymptomatic patient, which was originally considered an incidental hepatic hemangioma prior to being identified as a giant adrenal adenoma. Case description: The patient was a 54 year old obese female with a recent diagnosis of diabetes type II and dyslipidemia with recent ultrasound imaging suggestive of a hepatic hemangioma...

The globally prominent pathogen Streptococcus pyogenes secretes potent immunomodulatory proteins known as superantigens (SAgs), which engage lateral surfaces of major histocompatibility class II molecules and T-cell receptor (TCR) β-chain variable domains (Vβs). These interactions result in the activation of numerous Vβ-specific T cells, which is the defining activity of a SAg. Although streptococcal SAgs are known virulence factors in scarlet fever and toxic shock syndrome, mechanisms by how SAgs contribute to the life cycle of S...

An 8 mo old intact male mixed-breed dog presented for diphallia with paraphimosis of the nonfunctional, accessory penis. Bloodwork, an abdominal ultrasound, and a positive contrast retrograde urethrogram were performed and revealed no other structural abnormalities. Surgical excision of the accessory penis was elected. This is one of three reported cases of diphallia in the dog in the English literature, but this is the only case in which no other congenital abnormalities were identified. The authors also review diphallia in both the veterinary and human literature...

Novel staphylococcal enterotoxins (SEs) expressed by Staphylococcus aureus strains have been described throughout the years, among these being the SE protein SER. To further characterize this toxin, this research used 13 S. aureus strains previously determined to contain the SE type R (ser) gene. These S. aureus isolates were evaluated using serological assays for identification of SEA–SEE and PCR for the detection of newly described SE and SE-like enterotoxin genes seg–seu. PCR-based cloning was performed such that the ser gene could be ligated into the pTrc99A plasmid expression vector...

BACKGROUND AND PURPOSE: Trials of restorative therapies after stroke and clinical rehabilitation require relevant and objective efficacy end points; real-world upper extremity (UE) functional use is an attractive candidate. We present a novel, inexpensive, and feasible method for separating UE functional use from nonfunctional movement after stroke using a single wrist-worn accelerometer. METHODS: Ten controls and 10 individuals with stroke performed a series of minimally structured activities while simultaneously being videotaped and wearing a sensor on each wrist that captured the linear acceleration and angular velocity of their UEs...

One obstacle to the application of immunotherapy to solid malignancies is to overcome the existing tolerance to self-antigens. Vaccine strategies aimed at harnessing endogenous antitumor T cells are limited by the T-cell receptor repertoire, which can be detected within the thymus as central tolerance or rendered nonfunctional by post-thymic mechanisms of peripheral tolerance. Adoptive immunotherapy can overcome these obstacles, since therapeutically effective T cells can be engineered to recognize tumors. Continued advancements in novel treatments, including immunotherapy, in solid malignancies are imperative...

REVIEW
Vidya Aluri, Joseph S Dillon
Neuroendocrine cells are widely distributed throughout the body. They can produce, store, and secrete peptides and biogenic amines. Neuroendocrine tumors (NETs) are rare, but most are found in the intestine, pancreas, and lung. NETs may cause specific hormonal symptoms (eg, carcinoid syndrome) or appear nonfunctional. Blood or urine concentrations of tumor-secreted amines and peptides have been used as biomarkers in the diagnosis and management of NETs. This article focuses on currently available biochemical testing of blood or urine for gastroenteropancreatic and lung NETs and discusses the limitations of these tests and the potential role of newer multianalyte markers for NET management...

The phytoplasma associated with witches' broom disease of loofah [Luffa aegyptica Mill., syn. Luffa cylindrica (L.) M.J. Roem.] in Taiwan was classified in group 16SrVIII, subgroup A (16SrVIII-A), based on results from actual and in silico RFLP analysis of 16S rRNA gene sequences. Nucleotide sequencing of PCR-amplified, cloned DNA segments revealed rrn interoperon sequence heterogeneity in the loofah witches' broom (LfWB) phytoplasma. Whereas the 16S-23S rRNA spacer region of rrnA contained a complete tRNA-Ile gene, the spacer of rrnB contained a nonfunctional remnant of a tRNA gene...

Lung volume reduction surgery (LVRS) is an option for emphysematous patients who are awaiting lung transplantation. LVRS reduces nonfunctional portions of lung tissues and favors the compensatory lung growth (CLG) of the remaining lobes. This phenomenon diminishes dyspnea and improves both the respiratory mechanics and quality of life for the patients. An animal model of elastase-induced pulmonary emphysema was used to investigate the structural and functional lung response after LVRS. Bilobectomy was performed six weeks after elastase instillation...

Determinants of nonfunctional arteriovenous (AV) access, including timing of AV access creation, have not been sufficiently described. We studied 29 945 patients who had predialysis AV access placement and were included in the French REIN registry from 2005 through 2013. AV access was considered nonfunctional when dialysis began with a catheter. We estimated crude and adjusted odds ratio (OR) with 95% confidence intervals (CI) of nonfunctional versus functional AV access associated with case-mix, facility characteristics, and timing of AV access creation...

Multicystic renal dysplasia (MCRD) is the most common cause of abnormally enlarged kidney, diagnosed on antenatal ultrasound examination. It is an abnormality of the embryonic development in which the renal parenchyma is substituted by nonfunctioning renal tissue made up of cysts which do not communicate with each other. Vesicoureteric reflux (VUR), pelviureteric junction obstruction, vesicoureteric junction obstruction, and ureterocele are the most commonly seen abnormalities in contralateral kidney. Here, we report a case of prenatal diagnosis of unilateral MCRD with VUR in contralateral kidney...

RATIONALE: Genetic elucidation of cone-dominated retinal dystrophies in Indian subcontinent is much needed to identify and catalog underlying genetic defects. In this context, the present study recruited a consanguineous Indian family affected with autosomal recessive cone dystrophy (CD). Considering the huge genetic heterogeneity and recessive inheritance of the disease, we chose to dissect out causal variant in this family by whole exome sequencing (WES). PATIENT CONCERNS: In the recruited family, three of the six siblings had complaints of poor visual acuity, photophobia, and disturbed colour vision since early childhood...

Comparative analysis of the parameters of LPO, antioxidant defense (AOD), and the thiol/disulfide system was performed in fertile and infertile males of reproductive age carrying different genotypes of the glutathione system genes. Blood plasma, blood hemolysate, and ejaculate served as specimens for biochemical studies. A decrease in glutathione S-transferase activity was found in blood and ejaculate specimens from fertile and infertile carriers of nonfunctional GSTT1(0/0)/GSTM1(0/0) genotypes. In infertile carriers of nonfunctional GSTT1(0/0)/GSTM1(0/0) genotypes determining reduced glutathione S-transferase activity, a decrease in the concentration of low-molecular-weight cell antioxidant (reduced glutathione) and an increase in the concentration of secondary LPO products (TBA-reactive substances) were revealed...

The clinical success of tyrosine kinase inhibitors specific for BCR-ABL-, EGFR-, ALK-, and ROS1-driven cancers continues to spur the quest to match specific oncogene-defined tumor types with an appropriate molecularly targeted therapy. Unfortunately, responses to these agents are not durable with intrinsic or acquired resistance limiting benefit. Additionally, efforts to identify the appropriate targets of new drugs have focused on nonfunctional assays such as large-scale sequencing for somatic mutations or analysis of gene copy number...
