T cell responses and clinical symptoms among infants with congenital cytomegalovirus infection.

BACKGROUNDCongenital cytomegalovirus (cCMV) infection can cause developmental impairment and sensorineural hearing loss (SNHL). To determine the relationship between immune responses to cCMV infection and neurologic sequelae, T cell responses were compared for their connection to clinical symptoms at birth and neurodevelopmental outcomes.METHODSThirty cCMV-infected and 15 uninfected infants were enrolled in a single-center prospective observational case-control study.

Antibody Titers Against Human Cytomegalovirus gM/gN and gB Among Pregnant Women and Their Infants.

Congenital CMV (cCMV) infection can affect infants born to mothers with preconceptional seroimmunity. To prevent cCMV due to nonprimary maternal infection, vaccines eliciting responses exceeding natural immunity may be required. Anti-gM/gN antibodies have neutralizing capacity and in animal models, but anti-gM/gN antibodies have not been characterized among seroimmune pregnant women.

Murine cytomegalovirus promotes renal allograft inflammation via Th1/17 cells and IL-17A.

Human cytomegalovirus (HCMV) infection is associated with renal allograft failure. Allograft damage in animal models is accelerated by CMV-induced T helper 17 (Th17) cell infiltrates. However, the mechanisms whereby CMV promotes Th17 cell-mediated pathological organ inflammation are uncharacterized.

Telecytopathology for on-site adequacy evaluation decreases the nondiagnostic rate in endoscopic ultrasound-guided fine-needle aspiration of pancreatic lesions.

Objective: Advances in digital imaging methods have resulted in use of telecytology in the immediate assessment of fine-needle aspiration (FNA) specimens. We retrospectively compared the nondiagnostic rate for endoscopic ultrasound-guided (EUS) FNA of pancreatic lesions in two groups: one with on-site evaluation for adequacy via telecytopathology and the other without on-site adequacy evaluation.

Subjects And Methods: All patients undergoing EUS-FNA of pancreatic lesions over a 2-year period were included.

The passage of Florida's Statute on Assisted Reproductive Technology.

Until 1993, there were no statutes in the United States covering gestational surrogacy contracts, disposition of stored embryos and gametes, parentage of children born from donated gametes and embryos, and the inheritance rights of cryopreserved embryos of deceased donors. In March 1993, the Florida Assisted Reproductive Technology Act was passed to address some of these issues and to minimize the expense and emotional cost of related courtroom proceedings. Authors of the bill believed that motherhood of a newborn in the eyes of the law should be determined by two factors: genetic inheritance and the original intent of the woman to become the parent of record.

Yohimbine and naloxone: effects on male rat sexual behavior.

We evaluated the effects of yohimbine (2 mg/kg) and naloxone (5 mg/kg), separately and in combination, on copulatory behavior in male rats. In Experiment 1, yohimbine evinced decrements in intromission frequency, ejaculation latency, and copulatory efficiency, whereas naloxone administration was followed by an increased ejaculation latency, and the combination of yohimbine plus naloxone was without effect. In Experiment 2, yohimbine evinced decreases in intromission frequency, ejaculation latency, copulatory efficiency in the first, but not subsequent, copulatory series, as well as a decreased latency to sexual exhaustion.

Clozapine for psychosis in Parkinson's disease.

The clinical efficacy of clozapine, an atypical antipsychotic, in treating levodopa-induced hallucinations was investigated in five patients with Parkinson's disease under open label conditions. Two patients could not tolerate clozapine, even in doses as low as 12.5-25 mg daily, because of extreme sedation.

Somatosensory evoked potentials elicited by dorsal penile and posterior tibial nerve stimulation.

SEPs were elicited by stimulation of the dorsal penile nerve (DPN) or posterior tibial nerve (PTN) under 3 conditions of stimulation: random and constant interstimulus intervals, and subject-initiated stimulation. Within these conditions, the effects of repeated stimulation were also examined. The latency of the N90 peak decreased with repeated stimulation.

Neuroendocrine responses to exogenous estrogen: no differences between heterosexual and homosexual men.

Plasma LH concentrations were determined in 55 men before and for four days following injection of 10 mg, 20 mg, or 30 mg Premarin or a placebo injection of vehicle. Testosterone (T) and dihydrotestosterone (DHT) concentrations were also determined in plasma samples taken just prior to Premarin or placebo injection and in samples taken three days later. All subjects provided self-descriptions of their sexual orientation and, based upon these descriptions, were classified as heterosexual (N = 39) or homosexual (N = 16).

Brain structure and function in sexual molesters of children and adolescents.

Sixteen men incarcerated in a state psychiatric facility pursuant to sexual molestation of children and/or adolescents were evaluated by computed tomography (CT) head scans and regional cerebral blood flow (rCBF) estimation. Compared with controls, child molesters were found to have thinner and less dense skulls and lower rCBF values. Variations from control values in rCBF and characteristics of CT head scans for the sex offenders suggest a role for cerebral dysfunction in the etiology of their aberrant behavior.

A thirteenth cranial nerve: the cloacal nerve.

The completion by vertebrates of micturition, defecation, and copulation via the cloaca or its derivatives is hypothesized to be best explained by the existence of a thirteenth cranial nerve, the cloacal nerve, which, similar to the facial and trigeminal nerves, functions as a mixed cranial nerve containing both general and special components.

Neuropsychological deficit and regional cerebral blood flow in schizophrenic patients.

The paper examined the relationship between the scales of the Luria Nebraska Neuropsychological Battery and measures of cerebral blood flow in a sample of 51 chronic schizophrenic patients without a history of brain damage. Of 88 correlations between the two sets of data, 22 were significant at the .05 level.

Distribution of chlorpromazine and imipramine in adipose and other tissues of rats.

Adipose tissue kinetics of chlorpromazine and imipramine, two drugs which are more lipophilic than thiopental, were studied in the rat. After single i.v.

Aging and performance on the Luria-Nebraska neuropsychological battery.

The Luria-Nebraska Battery has been shown to be a valid measure of neuropsychological functioning in younger adults; however, little validity research with the elderly has been reported. Seventy-eight healthy elderly adults (mean age = 72.2 years) were tested with the Luria-Nebraska Battery and 92% of the profiles were found to be within normal limits.

Regional cerebral blood flow in schizophrenics. Tests using the xenon Xe 133 inhalation method.

Measurements of intrahemispheric and bilateral regional cerebral blood flow (CBF) for gray and white matter were compared in 29 schizophrenic patients and 22 normal controls, using the xenon Xe 133 inhalation method. Results showed significantly lower CBF values for all brain regions in the schizophrenic group, and post hoc comparisons showed relatively greater reduced gray-matter CBF values in the anterior areas of the brain. There was also a left-hemisphere frontal loss similar to that reported previously, although it was in the context of a generalized loss in anterior functioning.

Effect of alcohol ingestion on regional cerebral blood flow.

Regional distribution of cerebral blood flow was assessed in 10 normal social drinkers following consumption of .75 g/kg alcohol and in a control session without alcohol. Alcohol increased blood flow in the gray matter in all brain areas except the left anterior area.

Brain damage among mentally disordered sex offenders.

The incidence and nature of structural brain dysfunction was investigated in a pilot study sample of individuals currently assigned the Nebraska Penal Code designation of mentally disordered sexual offender. It was hypothesized that the sexual offenders would show a significantly higher incidence of dysfunction than a psychosocially normal group as evidenced by computed tomography scan measures, regional cerebral blood flow, and neuropsychological instruments. The hypothesis was tested by two different methods.
