Necrotizing enterocolitis in Black neonates.

Only registered users can translate articles

Several years ago neonatal necrotizing enterocolitis (NNE) was commonly seen in an open ward for premature babies at Baragwanath Hospital, which was affected by recurrent outbreaks of gastro-enteritis and Salmonella infections. Since outbreaks of infection have been prevented, NNE has been uncommon,

Regulation of respiration: "The Black Box".

Only registered users can translate articles

A close relation between the state of wakefulness, the electroencephalogram, and the respiration has been demonstrated (Bülow 1963). In the present paper it was assumed that as opening and closing of the eyes influence the EEG and thus probably the state of wakefulness, the responsiveness of the

Hypoxia impairs embryo development and survival in black bream (Acanthopagrus butcheri).

Only registered users can translate articles

Coastal environments are threatened by the increasing frequency, extent and severity of hypoxic events. Hypoxia affects vast areas around the world and often causes fish kills, reduced abundance, altered distribution, low benthic biomass and declines in fisheries. In Australia, many fisheries are

Reliability of noninvasive oximetry in black subjects during exercise and hypoxia.

Only registered users can translate articles

The effect of skin pigmentation on the reliability of noninvasive oximetry, especially during exercise and hypoxia, has not been thoroughly investigated. This is the first study, to our knowledge, that specifically addresses this question. Thirty-three young black men performed multistage,

[Haemoglobin system of Black Sea round goby under experimental hypoxia conditions].

Only registered users can translate articles

Haemoglobin of the Black Sea round goby (Neogobius melanostomus P.) resisting to external hypoxia was studied. Haemoglobin of this species was fractionated into 4 components (2 minor and 2 major ones) by the disk-electrophoresis in polyacrylamid gel. The major fractions were eluted and their

Greater performance impairment of black runners than white runners when running in hypoxia.

Only registered users can translate articles

This study aimed to compare the response of performance-matched black and white runners during maximal and sub-maximal running in normoxic and hypoxic conditions. 14 well-trained runners (8 black, 6 white) performed 2 incremental maximal exercise tests and 2 fatigue resistance tests at 21% O2

Physiological effects of medetomidine-zolazepam-tiletamine immobilization in black bears.

Only registered users can translate articles

A combination of medetomidine-zolazepam-tiletamine (MZT) was used to immobilize four black bears (Ursus americanus). The drugs were used at a dose of approximately 52 micrograms/kg of medetomidine, 0.86 mg/kg of zolazepam, and 0.86 mg/kg of tiletamine. Induction occurred in 6.3 +/- 3.3 min (mean +/-

Association Between Sleep Apnea and Blood Pressure Control Among Blacks.

Only registered users can translate articles

Blacks have a high prevalence of hypertension and uncontrolled blood pressure (BP), each of which may be partially explained by untreated sleep apnea. We investigated the association of sleep apnea with uncontrolled BP and resistant hypertension in

Hypoxia causes preservation of labile organic matter and changes seafloor microbial community composition (Black Sea).

Only registered users can translate articles

Bottom-water oxygen supply is a key factor governing the biogeochemistry and community composition of marine sediments. Whether it also determines carbon burial rates remains controversial. We investigated the effect of varying oxygen concentrations (170 to 0 μM O2) on microbial remineralization of

Childhood sudden death secondary to accidental aspiration of black pepper.

Only registered users can translate articles

The case history is presented of a 4-year-old boy, with a history of pica, who aspirated table pepper with subsequent respiratory arrest, severe anoxia, and death. We believe this to be the first case reported in the literature of fatal accidental aspiration of pepper.

The effect of ocean warming on black sea bass (Centropristis striata) aerobic scope and hypoxia tolerance.

Only registered users can translate articles

Over the last decade, ocean temperature on the U.S. Northeast Continental Shelf (U.S. NES) has warmed faster than the global average and is associated with observed distribution changes of the northern stock of black sea bass (Centropristis striata). Mechanistic models based on physiological

Association of a hypoxia-inducible factor-3α gene polymorphism with superovulation traits in Changbaishan black cattle.

Only registered users can translate articles

This study was designed to examine a single nucleotide polymorphism (SNP) in the HIF-3α gene in three hundred Changbaishan black cattle using PCR-restriction fragment length polymorphism to determine whether there is an association between this SNP and superovulation. The cloning and sequencing

Augmented chemosensitivity in black-eyed white Mitfmi-bw mice, lacking melanocytes.

Only registered users can translate articles

Microphthalmia-associated transcription factor (Mitf) is responsible for differentiation of melanocytes, and a recessive Mitf mutant, black-eyed white (bw) mouse, is characterized by the lack of melanocytes in the skin and inner ear. To search for the hitherto unknown roles of melanocytes, we

The influence of acute hypoxia on the functional and morphological state of the black scorpionfish red blood cells.

Only registered users can translate articles

The investigation of the mechanisms of red blood cell steadiness to the oxygen lack in tolerant teleosts is of current scientific interest. Black scorpionfish, Scorpaena porcus L., is a widespread benthal species in the Black Sea and is highly resistant to hypoxic influence. The morphological state

Effects of simulated altitude and exercise upon ECGs of young black men.

Only registered users can translate articles

Twenty-five healthy black men between 17 and 21 years of age were evaluated. Their resting and exercise electrocardiograms were recorded at simulated sea level and at a simulated altitude of 4,000 m. Sea level exercise caused a reduction in the amplitudes of R waves and a lowering of J points.
