In normal subjects, maximum voluntary contraction (MVC) and electrical ulnar nerve stimulation (UNS; 30-Hz bursts of 0.33 s) were systematically compared with regard to the forces generated in different directions (abduction/adduction and flexion) and at different degrees of index finger abduction. With a “resting” hand position in which there was no index finger abduction, UNS produced about one-half of the abduction force elicited by an MVC (mean ratio 51%). Qualitatively, such a discrepancy would be expected, because UNS activates two index finger muscles with opposing actions in the abduction/adduction plane of torques: the first dorsal interosseus (FDI) and the first palmar interosseus (FPI). The abduction forces produced by MVC and UNS were very sensitive to index finger abduction angle: at a maximum degree of abduction, the UNS-generated force even reversed its direction of action to adduction (with FPI dominating) and the abduction MVC declined to 37% of that in the resting hand position. Inasmuch as these declines in MVC- and UNS-generated abduction force could not be explained by a change in moment arm, the main alternative seemed to be abduction-associated alterations in FDI fiber length (analysis by previously published biomechanical data). The FDI and FPI were further compared by application of a UNS-generated fatigue test (5-min burst stimulation), with the index finger kept at a "neutral" angle, i.e., the abduction angle at which, in the unfatigued state, the forces of the FDI and FPI were in balance (zero net UNS-generated abduction/adduction force).(ABSTRACT TRUNCATED AT 250 WORDS)

1. The patterns of muscle activity during warm-up were compared to those of flight. In the skipper Hylephila phylaeus and in the hawk moths Celerio lineata and Mimas tiliae the intervals between bursts of muscle potentials are the same as the wingbeat periods of flight at the same thoracic temperature, and the burst length is the same as in flight. In saturniids the period and burst length are both shorter during wing-vibrating than during flight. 2. During wing-vibrating the amplitude of the wing movement is small, and some of the muscles which are antagonists in flight are active simultaneously. In Hylephila phylaeus and Celerio lineata there is a phase change between some synergistic muscles, while some antagonistic pairs retain the phase relationships of flight. During wing-vibrating in Mimas tiliae and in saturniids all the motor units sampled were active at the same time. 3. In M. tiliae a variety of phase relationships intermediate between those of wing-vibrating and flight were observed, including a case of ‘relative co-ordination’ between motor units in the mesothorax. The results exclude the possibility that a single pace-making centre drives the motor neurons in the flight pattern. 4. A model of the central nervous interactions which generate the observed motor patterns is proposed. It is postulated that a small group of positively coupled neurons produces bursts of impulses at the wingbeat frequency and that these groups interact to generate the phase relationships seen during warm-up and flight.

AbstractTelomere length (TL) regulation is an important factor in ageing, reproduction and cancer development. Genetic, hereditary and environmental factors regulating TL are currently widely investigated, however, their relative contribution to TL variability is still understudied. We have used whole genome sequencing data of 250 family trios from the Genome of the Netherlands project to perform computational measurement of TL and a series of regression and genome-wide association analyses to reveal TL inheritance patterns and associated genetic factors. Our results confirm that TL is a largely heritable trait, primarily with mother’s, and, to a lesser extent, with father’s TL having the strongest influence on the offspring. In this cohort, mother’s, but not father’s age at conception was positively linked to offspring TL. Age-related TL attrition of 40 bp/year had relatively small influence on TL variability. Finally, we have identified TL-associated variations in ribonuclease reductase catalytic subunit M1 (RRM1 gene), which is known to regulate telomere maintenance in yeast. We also highlight the importance of multivariate approach and the limitations of existing tools for the analysis of TL as a polygenic heritable quantitative trait.

Background. Squamous cell lung cancer (SCLC) is the most common form of lung cancer among men smokers. Mediators and products of inflammation can contribute to the initiation of carcinogenesis in smokers. The aim of study is to investigate the association between IL1B(rs1143634, rs16944), IL1RN (rs2234663), TNFA (rs1800629), IL6 (rs1800795), IL10 (rs1800896) genes and SCLC depending on the duration of smoking in men. Materials and methods. We studied 324 patients with SCLC and 168 healthy men smokers. The typing of the IL1RN(rs2234663) gene polymorphism has analyzed by polymerase chain reaction (PCR). Detection of the IL1B (rs1143634) and IL6 (rs1800795) polymorphisms have performed by restriction fragment length analysis, as a restriction enzyme TaqI was used. The IL1B (rs16944), TNFA(rs1800629) and IL10 (rs1800896) genes polymorphisms have determined through TaqMan-real-time PCR. Results. The study showed, the age, duration of smoking and the number of cigarettes smoked per day were the main risk factors for SCLC in men (p < 0.0001). The IL6 -174G allele was detected an additional risk factor of SCLC at a smoking duration of less than 35 years (OR = 1.68; 95 % CI: 1.12-2.51; pcor = 0,04). No association of IL1B (rs1143634, rs16944), IL1RN (rs2234663), TNFA (rs1800629), and IL10 (rs1800896) genes with the risk of SCLC in men was identified. Conclusion. The duration of smoking and rs1800795 IL6 gene polymorphism may influence on the susceptibility to SCLC in men. Our results can be useful in understanding the molecular mechanisms of development of SCLC.
