Abstract
Traumatic brain injury (TBI) is one of the leading causes of death worldwide. There are currently no effective treatments for TBI, and trauma survivors suffer from a variety of long-lasting health consequences. With nutritional support recently emerging as a vital step in improving TBI patients' outcomes, we sought to evaluate the potential therapeutic benefits of nutritional supplements derived from bovine thymus gland, which can deliver a variety of nutrients and bioactive molecules. In a rat model of controlled cortical impact (CCI), we determined that animals supplemented with a nuclear fraction of bovine thymus (TNF) display greatly improved performance on beam balance and spatial memory tests following CCI. Using RNA-Seq, we identified an array of signaling pathways that are modulated by TNF supplementation in rat hippocampus, including those involved in the process of autophagy. We further show that bovine thymus-derived extracts contain antigens found in neural tissues and that supplementation of rats with thymus extracts induces production of serum IgG antibodies against neuronal and glial antigens, which may explain the enhanced animal recovery following CCI through possible oral tolerance mechanism. Collectively, our data demonstrate, for the first time, the potency of a nutritional supplement containing nuclear fraction of bovine thymus in enhancing the functional recovery from TBI.

Abstract
Saponins, prominent secondary plant metabolites, are recognized for their roles in plant defense and medicinal benefits. Soyasaponins, commonly derived from legumes, are a class of triterpenoid saponins that demonstrate significant potential for plant and human health applications. Previous research and reviews largely emphasize human health effects of soyasaponins. However, the biological effects of soyasaponins and their implications for plants in the context of human health have not been well-discussed. This review provides comprehensive discussions on the biological roles of soyasaponins in plant defense and rhizosphere microbial interactions; biosynthetic regulation and compound production; immunological effects and potential for therapeutics; and soyasaponin acquisition attributed to processing effects, bioavailability, and biotransformation processes based on recent soyasaponin research. Given the multifaceted biological effects elicited by soyasaponins, further research warrants an integrated approach to understand molecular mechanisms of regulations in their production as well as their applications in plant and human health.

Abstract
BACKGROUND Multiple endocrine neoplasia type 2 (MEN 2) and familial medullary thyroid carcinoma (FMTC) are autosomal dominantly inherited cancer syndromes that predispose to C-cell hyperplasia and MTC. MEN 2A and FMTC are caused by mutations in the RET proto-oncogene. METHODS We used a multiplex polymerase chain reaction-based assay to screen exons 10, 11, 13, and 14 of RET for mutations in 2 families with FMTC. We correlated mutation status with calcitonin and pathologic studies to determine genotype-phenotype correlations. RESULTS We identified a mutation in codon 804 in exon 14 (GTG-->ATG; V804M) in both families. An 86-year-old person who was a gene carrier and other individuals over age 70 who were suspected by pedigree analysis to be gene carriers had no overt clinical evidence of MTC. Four of 21 patients who underwent a thyroidectomy also had papillary thyroid cancer. One individual in each family had metastatic MTC at age 30 and 32 years, and all 26 people having thyroidectomies had either MTC or C-cell hyperplasia, leading us to continue to recommend prophylactic thyroidectomy for all identified patients who were gene carriers. CONCLUSIONS Because of active MTC in younger members of these families, including metastases, we have continued to advocate thyroid surgery in mutation-positive individuals. While DNA diagnosis of gene carriers and subsequent genetic counseling was relatively straightforward, the acceptance of surgical recommendations was more difficult for some individuals. These families demonstrate that the search for RET mutations should include exons 13, 14, 15, and 16 in patients whose studies in exons 10 and 11 are negative.

Abstract
A series of compounds related to oxathiin carboxanilide has been identified as nonnucleoside reverse transcriptase inhibitors (NNRTIs) of HIV-1, and structure-activity relationships have been described (Buckheit RW, et al.: Antimicrob Agents Chemother 1995;39:2718-2727). Three new analogs (UC040, UC82, and UC781) inhibited laboratory and clinical isolates of HIV-1, including isolates representative of the various clades of HIV-1 found worldwide, in both established and fresh human cells. Virus isolates with the amino acid changes L100I, K103N, V106I, and Y181C in the reverse transcriptase were partially resistant to these compounds. However, UC781 inhibited these virus isolates at low nontoxic concentrations, presenting a broad in vitro therapeutic index. As with other NNRTIs, each of the compounds synergistically interacted with AZT to inhibit HIV-1 replication. UC781 possesses a favorable pharmacokinetic profile in mice with a high level of oral bioavailability. Plasma concentrations reached maximum levels within 2 to 4 hr of oral administration and remained in excess of those required for in vitro anti-HIV activity for at least 24 hr after a single oral dose. When evaluated in a murine hollow fiber implant model of HIV infection, UC781 dosed orally or parenterally was able to suppress HIV replication completely in this model system, providing evidence of the in vivo efficacy of the compound.

Abstract
Staphylococcus aureus is an etiological agent of a wide variety of human and animal infections. The majority of S. aureus are coagulase-positive; however, some may be atypical in that they do not produce coagulase. Incorrect identification of an isolate can impact implementation of effective treatment and/or control measures. In this study, polymerase chain reaction-based DNA fingerprinting was used to differentiate coagulase-positive Staphylococcus aureus (CPSA) from coagulase-negative Staphylococcus aureus (CNSA). A total of 29 CNSA and 50 CPSA were evaluated. PCR-based DNA fingerprinting differentiated CNSA from CPSA on the basis of visible observation and densitometric evaluation. The method is rapid and accurate, eliminating variability associated with conventional techniques.

Abstract
In patients with the 3p-syndrome, hemizygous deletion of 3p25-pter is associated with profound growth failure, characteristic facial features, and mental retardation. We performed a molecular genetic analysis of 3p25 breakpoints in four patients with the 3p- syndrome, and a fifth patient with a more complex abnormality, 46,XY,der(3)t(3;?)(p25.3;?). EBV transformed lymphoblasts from each of the patients were initially characterised using fluorescent in situ hybridisation (FISH) and polymorphic microsatellite analyses. The 3p-chromosome from each patient was isolated from the normal chromosome 3 in somatic cell hybrid lines and subsequently analysed with polymorphic and monomorphic PCR amplifiable markers from 3p25. The analysis clearly shows that all five breakpoints are distinct. Furthermore, we have identified yeast artificial chromosomes that cross the 3p25 breakpoints of all four 3p-patients. Two of the patients were deleted for the von Hippel-Lindau (VHL) tumour suppressor gene, although neither has yet developed evidence of VHL disease. The patient with the most centromeric breakpoint, between D3S1585 and D3S1263, had the most severe clinical phenotype including an endocardial cushion defect that was not observed in any of the four patients who had more telomeric breakpoints. This study should provide useful insights into critical regions within 3p25 that are involved in normal human growth and development.

Abstract
PURPOSE Cannabis Sativa (marijuana) may cause a variety of respiratory disorders including uvular oedema. This case illustrates that uvular oedema secondary to marijuana inhalation may cause a potentially serious postoperative clinical problem. CLINICAL FEATURES A healthy 17-yr-old man who inhaled marijuana prior to general anaesthesia. In the recovery room, after an uneventful general anaesthetic, acute uvular oedema resulted in post operative airway obstruction and admission to hospital. The uvular oedema was treated successfully with dexamethasone. CONCLUSION Recent inhalation of marijuana before general anaesthesia may cause acute uvular oedema and post operative airway obstruction. The uvular oedema can be easily diagnosed and treated.

Abstract
A new application of auditory evoked potentials using direct cochlear nerve action potentials (CNAPs) for monitoring middle fossa acoustic neuroma resection with attempted hearing preservation is described. Twenty patients have been studied to date. With this technique, a monitoring electrode is secured between the floor of the internal auditory canal and the dura adjacent to the cochlear nerve in an extradural location. Standard auditory evoked potential techniques with click stimuli and microelectrical recording allow observation of nearfield waveforms in seconds versus several minutes required for farfield potentials recorded from the scalp. Advantages of this technique over auditory brainstem response monitoring may include nearly real time measurement of potentials, improved surgeon learning curve and possibly higher rates of hearing preservation, and applicability to all patients undergoing hearing-preservation surgery independent of presence or absence of ABR tracing. Immediate changes in amplitude and latency of waveforms appear to compare with reversible and irreversible intraoperative auditory system damage, thereby guiding surgical maneuvers.

Abstract
Previous studies demonstrated that human cell lines can be cultivated in hollow fibers in the subcutaneous and intraperitoneal compartments of mice. We have extended the range of cell lines to include cells infected with the human immunodeficiency virus (HIV). Furthermore, these HIV-infected cells have been shown to replicate in the hollow fibers located in both physiologic compartments (intraperitoneal and subcutaneous) of SCID mice. Treatment of the host mice with antiviral agents can suppress virus replication in these hollow fiber cultures. The potential use of this system for early in vivo screening of anti-HIV compounds is discussed.

Abstract
Six murine hybridoma cell lines producing monoclonal antibodies (MAbs) specific for Toxin B of Clostridium difficile have been generated from toxin-immunized female RBF/DnJ mice. All six antibodies were reactive in Western blots with a > 200-kD protein in the supernatants of the toxigenic strain 10463 and were unreactive with similarly prepared material from the nontoxigenic strain 2037. Polyclonal antisera from rabbits immunized with Toxin B reacted on Western blots primarily with Toxin B, a 40-kD and a 55-kD band with a minor set of triplet bands at approximately 100 kD. None of the MAbs reacted in a direct EIA with purified Toxin A from C. difficile but two MAbs reacted weakly with a trypsin-sensitive band (> 200 kD) in Western blots of C. sordellii. Polyclonal antisera developed against Toxin B reacted strongly with supernatants from C. sordellii, C. bifermentans, and the nontoxigenic strain 2037. Toxin B-specific antisera was unreactive with supernatants from C. perfringens or purified Toxin A from C. difficile in direct EIA. Toxin B-specific MAbs linked to an affinity column were able to deplete bacterial supernatant of cytotoxigenic activity.

Abstract
We describe a 4-year-old boy with an interstitial deletion of the long arm of chromosome 10: del(10) (q11.2q22.1). Frontal bossing, hypertelorism, bright blue iris color, up-slanting palpebral fissures, a flat nasal bridge, a broad nose, apparently low-set ears, micrognathia, deep philtrum, and hypotonia were noted neonatally. A murmur was noted at age 5 1/2 months and surgical repair of subaortic stenosis was required at 4 years. At 4 years micrognathia was no longer evident, but the palate was high-arched. The pattern of abnormalities included postnatal-onset slow growth, short stature, mental retardation, and cardiac anomalies.

Abstract
This study characterizes two- and three-dimensional ultrastructure and surface topography of polymerized networks of intermediate filaments (IF) isolated from mouse peritoneal macrophages. Isolated IF bound to monoclonal anti-IF antibodies in enzyme-linked immunosorbent assays. Immunogold labeling of IF with specific antibodies revealed that epitopes are distributed along filaments particularly at junctions where filaments interconnect. Networks of IF, viewed by scanning electron microscopy, organized as ropelike groups of interconnecting filaments which swirl and encircle each other to form three-dimensional lattices containing ellipsoidal-, circular-, and vacuole-shaped cavities. Cavity diameters were similar in size to organelles and vacuoles; diameters were grouped as small (12-288 nm), medium (0.3-1.7 micron), and large (2-3 micron). The walls of the cavities appeared as beaded structures with alternating globular and linear regions. Linear regions were 14 nm. Repeat distances taken from the central axis of globular regions were 23-27 nm. The lattice organization of IF observed in vitro was similar to images seen in vivo in Triton-insoluble cytoskeletons immunofluorescently labeled with specific antibodies. In whole cells processed for TEM, swirling bundles of IF were found encircling membranous vacuoles. Based on the lattice architecture of IF, cavity dimensions, and IF location, we postulate that intermediate filaments may function in the mechanical and spatial distribution of vacuoles in the cell cytoplasm.

Abstract
The importance of peritoneal cytology was investigated in 163 patients with squamous cell carcinoma of the cervix. Of 116 patients undergoing primary evaluation and treatment 3 (2.5%) had abnormal cytology. No abnormal specimens were found in 77 patients undergoing radical hysterectomy. Five (10.6%) of forty-seven patients evaluated and treated for posttreatment recurrence had abnormal cytology. All eight patients with abnormal cytology had other poor prognostic factors and are dead of cancer. The relevance of abnormal cytology is discussed.

Abstract
This series is composed of 47 patients who underwent immediate, early, or late postoperative prosthetic fitting after upper-limb amputation. The purpose of this review was to analyze the impact of rapid postoperative fitting on upper-limb amputation, and to assess general prosthetic prescription and guidelines for upper-limb amputees. It would appear that in adult amputations there is a "Golden Period" of fitting for upper-limb prosthetic devices and this period appears to be within the first month after amputation. There appears to be no difference in ultimate prosthetic acceptance rate or use patterns as a function of the type of prosthesis initially provided. Based upon this combined review between the Tucson and Atlanta VA Medical Centers, the authors would suggest that all upper-limb amputees be fitted as rapidly as possible (within 30 days) with conventional prosthetic devices, and when they have shown motivation and skill in the use of conventional devices, then to re-evaluate them for appropriate externally powered prosthetic components.
