Thus, U. rigida exhibited a decrease in photosynthesis under acidification, changing LN, and AT+4 °C. These results emphasize the importance of studying the interaction between environmental parameters using in-situ versus ex-situ conditions, when aiming to evaluate the impact of global change on marine macroalgae.

A narrow base of gait (BOG), the mediolateral distance between the foot and the body's line of gravity at midstance, during running is a suggested cause of injuries such as iliotibial band syndrome and tibial stress injury. However, an understanding of modifiable and nonmodifiable factors that influence BOG is lacking, which limits the development of corrective strategies.

To determine if BOG varies by sex and running speed and the influence of running kinematics and anthropometrics on BOG.

Cross-sectional study.

Record review of routinely collected performance data from a National Collegiate Athletic Association Division I intercollegiate athletic program.

A total of 166 Division I collegiate athletes (basketball, cross-country, football, soccer).

Running biomechanics (N = 166) and dual-energy x-ray absorptiometry-derived anthropometric data (n = 68) were extracted. Running variables were BOG, step rate, stride length, foot-inclination angle, center-of-mass vertical displacement, heel-to-center o the appropriateness of an individual's BOG. Additionally, BOG was associated with several potentially modifiable kinematic parameters.

Sex and running speed must be considered when determining the appropriateness of an individual's BOG. Additionally, BOG was associated with several potentially modifiable kinematic parameters.Identifying determinants of HIV reservoir levels may inform novel viral eradication strategies. Cytomegalovirus (CMV) and Epstein-Barr virus (EBV) co-infections were assessed as predictors of HIV proviral DNA level in 26 HIV RNA-suppressed Kenyan children starting antiretroviral therapy (ART) before 7 months of age. Earlier acquisition of CMV and EBV, and higher cumulative burden of systemic EBV DNA viremia were each associated with higher HIV DNA level in the reservoir after 24 months of ART, independent of HIV RNA levels over time. These data suggest delaying or containing CMV and EBV viremia may be novel strategies to limit HIV reservoir formation.Wheat (Triticum aestivum L.) root growth in the subsoil is usually constrained by soil strength, although roots can use macropores to elongate to deeper layers. The quantitative relationship between the elongation of wheat roots and the soil pore system, however, is still to be determined. We studied the depth distribution of roots of six wheat varieties and explored their relationship with soil macroporosity from samples with the field structure preserved. Undisturbed soil cores (to a depth of 100 cm) were collected from the field and then non-destructively imaged using X-ray computed tomography (at a spatial resolution of 90 µm) to quantify soil macropore structure and root number density (the number of roots cm-2 within a horizontal cross-section of a soil core). Plerixafor Soil macroporosity changed significantly with depth but not between the different wheat lines. There was no significant difference in root number density between wheat varieties. In the subsoil, wheat roots used macropores, especially biopores (i.e. former root or earthworm channels) to grow into deeper layers. Soil macroporosity explained 59% of the variance in root number density. Our data suggested that the development of the wheat root system in the field was more affected by the soil macropore system than by genotype. On this basis, management practices which enhance the porosity of the subsoil may therefore be an effective strategy to improve deep rooting of wheat.

Fear has been cited as the primary barrier for return to sport (RTS) after anterior cruciate ligament reconstruction (ACLR). Understanding the neural factors contributing to fear after ACLR may help identify interventions for this population.

The objective of this study was to characterize the underlying neural substrate of injury-related fear in patients after ACLR versus healthy matched controls during a picture imagination task (PIT) consisting of sports-specific images and activities of daily living images.

Case-Control Study Setting Research Laboratory Patients or Other Participants A total of 24 right-hand dominant participants (12 left-sided ACLR and 12 controls) were enrolled. Participants underwent full brain functional magnetic resonance imaging (fMRI).

Functional data were acquired with Blood Oxygen Level Dependent (BOLD) echoplanar imaging. Independent t-tests were used to identify significant between group differences in BOLD signal changes during all images of the PIT. Paired t-tests werfor sports-specific activities and activities of daily living. Psychosocial interventions may be warranted after ACLR to reduce injury-related fear and mitigate potentially maladaptive neuroplasticity after ACLR.A nine-year-old female Black-footed African penguin ( Spheniscus demersus ) was presented for necropsy after a history of reproductive abnormalities, paresis of limbs, weakness and sudden death. Post-mortem examination revealed soft keel, collapsed rib cage with beading of the ribs and bilateral parathyroid enlargement. Classical histological lesions of fibrous osteodystrophy with osteomalacia were observed in the ribs, vertebrae and to a lesser extent femur and tibiotarsus associated with hyperplasia of parathyroid glands. This represents the first report of nutritional secondary hyperparathyroidism in birds of the order Spheniciformes , most likely caused by low level of calcium supplementation during egg laying. The reproductive abnormalities observed in this penguin and others from the same group (asynchronous egg laying cycles, abnormal breeding behavior) were most likely exacerbated by the lack of an adequate photoperiod mimicking the natural daylight pattern.

Dendrobium huoshanense (DHS) is a typical traditional Chinese medicine with unique medical value and high economic, could be easily adulterated with the cheaper adulterations (Dendrobium henanese, DHN), because of their similar appearances and tastes.

In this study, the cheap adulterated DHN in DHS was detected by near infrared (NIR) spectroscopy combined with chemometric methods.

By performing partial least squares (PLS), PLS multivariate methods including partial least-squares discriminant analysis (PLS-DA), and partial least-squares regressions (PLSR) were applied to the obtained spectral data to build models. The PLS-DA model was employed to differentiate between pure DHS samples and those adulterated with DHN.

The R2 value obtained for the PLS-DA model was 0.4898 with an RMSEP error of 0.1554. resulting in a 100% accuracy of validation sample sets. Similarly, a PLSR model was also developed to quantify the amount of DHN adulterant in DHS samples. Experimental results indicated that the good performance of the multiplicative scattering correction (MSC) model is the better model showed a prediction performance (RMSEP 2.
