Short-Latency Trigeminocervical Reflex Obtained Without Muscle Activation: Topographic Distribution and Methodological Approach.

Purpose: Electrical stimulation of trigeminal nerve branches elicits early and late reflex responses in the cervical muscles, known as the trigeminocervical reflex (TCR). This study aimed to evaluate the neurophysiological aspects, stimulation patterns, and topographic distribution of short-latency TCR components in humans in the absence of voluntary muscle activation.

Methods: This prospective observational study included 30 participants.

The feasibility and technical aspects of trigemino-cervical reflex elicitation in humans under general anesthesia.

Objective: To analyze the feasibility, neurophysiological aspects, stimulation patterns, and topographic distribution of trigemino-cervical reflex (TCR) components in humans under general anesthesia.

Methods: This prospective observational study enrolled 20 participants who underwent posterior fossa surgery, surgical proceduresin thecraniovertebral junction,or spinal cord surgery. TCR responses were simultaneously recorded in the sternocleidomastoid (SCM) and trapezius muscles after electrical stimulation of the supraorbital and infraorbital nerves.

Technical Aspects of Eliciting Trigeminocervical and Trigeminospinal Reflexes in Humans: A Scoping Review.

This scoping review aims to summarize the technical strategies for obtaining trigeminocervical reflex (TCR) and trigeminospinal reflex (TSR) responses. Studies published on TCR or TSR elicitation in humans through electrical stimulation of trigeminal nerve branches were eligible for this scoping review. The data of interest included stimulation parameters, site of stimulation, recording parameters, and the feasibility of TCR and TSR elicitation, in healthy participants.

The right to health in the territory: service users' perceptions of Primary Health Care.

Primary health care is an essential component of effective health systems. The aim of this study aim was to evaluate the quality of primary care in a city in the state of Pernambuco, Brazil. We conducted an exploratory study with 525 service users using structured questionnaires.

Biofeedback Therapies for Chronic Insomnia: A Systematic Review.

The treatment of insomnia is still a challenge in clinical practice. This systematic review of randomized and quasi-randomized clinical trials aims to summarize the evidence for the use of biofeedback techniques in the treatment of chronic insomnia. Studies that compared biofeedback with other techniques of cognitive behavioral therapy, placebo, or absence of treatment were selected.

Assessment of the responsiveness of a public health service from the perspective of older adults.

Objective: To assess the quality of health care of older adults using as a parameter the assessment of the responsiveness of the service.

Methods: This is a descriptive cross-sectional study conducted in a reference unit of the Brazilian Unified Health System at the outpatient level. The sample was probabilistic and had 385 older adults; data collection occurred in 2014.

An alternative conformation of ERβ bound to estradiol reveals H12 in a stable antagonist position.

The natural ligand 17β-estradiol (E2) is so far believed to induce a unique agonist-bound active conformation in the ligand binding domain (LBD) of the estrogen receptors (ERs). Both subtypes, ERα and ERβ, are transcriptionally activated in the presence of E2 with ERβ being somewhat less active than ERα under similar conditions. The molecular bases for this intriguing behavior are mainly attributed to subtype differences in the amino-terminal domain of these receptors.

[Use of the Mini-Mental State Examination in research on the elderly in Brazil: a systematic review].

The Mini-Mental State Examination (MMSE) is the most widely used cognitive screening test around the world. In Brazil, different MMSE versions and many cut-off points have been used. A systematic review of papers indexed in Scielo was conducted in order to analyze use of the MMSE in Brazilian empirical studies with elderly people.

Virulence of Metarhizium anisopliae and Beauveria bassiana to Ctenocephalides felis felis.

Ctenocephalides felis felis is a flea species that parasitizes dogs and cats. The current study verified the in vitro virulence of the entomopathogenic fungi Metarhizium anisopliae and Beauveria bassiana to eggs and adults of C. felis felis.

[Development of the fungi Metarhizium anisopliae (Metschnikoff, 1879) Sorokin, 1883 and Beauveria bassiana (Balsamo) Vuillemin, 1912 on the Ctenophephalides felis felis (Bouché, 1835)].

The flea Ctenocephalides felis felis is a parasite that causes allergic dermatitis and also may transmit etiologic agents to domestic animals and humans. This study investigated by scanning electron microscopy the development of entomopathogenic fungi on flea cuticle. Fleas were exposed to conidia (10(8) ml(-1)) of Metarhizium anisopliae (isolate 959) or Beauveria bassiana (isolate 986).

[In vitro patogenicity of the fungi Metarhizium anisopliae (Metschnikoff, 1879) Sorokin, 1883, on the tick Boophilus microplus (Canestrini,1887)].

The cattle tick Boophilus microplus is a serious concern to the Brazilian cattle industry. It causes decreased meat and milk production, low alimentary conversion, damage to leather and transmission of pathogens. The use of entomopathogenic fungi as biological control agents for ticks has shown promising results.

[In vitro pathogenicity of fungic formulation on nymphs and adults of Rhipicephalus sanguineus (Latreile, 1806) (Acari:Ixodidae)].

Rhipicephalus sanguineus is responsible for transmitting several pathogenic agents, such as: Babesia sp. and Ehrlichia sp..
