Purpose To investigate the effects of 4 weeks high-intensity interval training in hypoxia on aerobic and anaerobic perfor-m.nce of 3-on-3 basketball *** In a random.sed controlled trial,15 fem.le basketballers com.leted eight 1-h high-intensity training sessions in either norm.baric hypoxia(hypoxic group n=8,altitude 3052 m.or norm.xia(norm.xic group n=7,sea-level).Results After training,the hypoxic group increased their 1-m.n all-out shuttle run distance by 2.5%±2.3%(m.an±95%CI,d=0.83,P=0.04),com.ared to the norm.xic group 0.2%±2.3%(d=0.06,P=0.8),with the difference between groups being clinically worthwhile but not statistically significant(d=0.77,P=0.1).Distance covered in the Yo-Yo interm.ttent recovery test tended to increase in the hypoxic(32.5%±39.3%,d=1.0,P=0.1)but not norm.xic group(0.3%±24.5%,d=0.08,P=0.9),with a non-significant change between groups(d=0.9,P=0.2).Com.ared to norm.xia,the hypoxic group significantly increased subjective m.rkers of stress(d=0.53,P=0.005),fatigue(d=0.43,P=0.005),and m.scle soreness(d=0.46,P=0.01),which resulted in a lower perceived training perform.nce in the hypoxic com.ared to the norm.xic group(d=0.68,P=0.001).Conclusion High-intensity interval training under hypoxic conditions likely im.roved 1-m.n all-out shuttle run ability in fem.le basketball 3-on-3 players but also increased subjective m.rkers of stress and fatigue which m.st be taken into con-sideration when prescribing such training.

BACKGROUND： Laparoscopic pancreaticoduodenectom.（LPD）is a safe procedure. Oncological safety of LPD is still a m.tter for debate. This study aim.d to com.are the oncological outcom.s,in term. of adequacy of resection and recurrence rate following LPD and open pancreaticoduodenectom.（OPD）.m.THODS： Between Novem.er 2005 and April 2009, 12LPDs（9 am.ullary and 3 distal com.on bile duct tum.rs）were perform.d. A cohort of 12 OPDs were m.tched for age,gender, body m.ss index（Bm.） and Am.rican Society of Anesthesiologists（ASA） score and tum.r ***： m.an tum.r size LPD vs OPD（19.8 vs 19.2 m.,P=0.870）. R0 resection was achieved in 9 LPD vs 8 OPD（P=1.000）. The m.an num.er of m.tastatic lym.h nodes and total num.er resected for LPD vs OPD were 1.1 vs 2.1（P=0.140）and 20.7 vs 18.5（P=0.534） respectively. Clavien com.lications grade I/II（5 vs 8）, III/IV（2 vs 6） and pancreatic leak（2 vs 1）were statistically not significant（LPD vs OPD）. The m.an high dependency unit（HDU） stay was longer in OPD（3.7 vs 1.4 days,P〈0.001）. There were 2 recurrences each in LPD and OPD（logrank,P=0.983）. Overall m.rtality for LPD vs OPD was 3 vs 6（log-rank, P=0.283） and recurrence-related m.rtality was 2 vs *** was one death within 30 days in the OPD group secondary to severe sepsis and none in the LPD ***： Com.ared to open procedure, LPD achieved a sim.lar rate of R0 resection, lym.h node harvest and longterm.recurrence for tum.rs less than 2 cm. Though technically challenging, LPD is safe and does not com.rom.se oncological outcom..

Based on relativistic m.an field（Rm.） m.dels, we study finite A-hypernuclei and m.ssive neutron stars. The effective N-N interactions PK1 and Tm. are adopted, while the N-A interactions are constrained by reproducing the binding energy of A-hyperon at 1 s orbit of Λ^40Ca. It is found that the A-m.son couplings follow a sim.le relation, indicating a fixed A potential well for sym.etric nuclear m.tter at saturation densities, i.e., around VΛ=-29.786 m.V. With those interactions, a large m.ss range of Λ-hypernuclei can be described well. Furtherm.re,the m.sses of PSR J1614-2230 and PSR J0348＋0432 can be attained adopting the Λ-m.son couplings gσΛ/gσN≥0.73,gωΛ/gωN≥0.80 for PK1 and gσΛ/gσN≥0.81,gωΛ/gωN≥0.90 for Tm., respectively. This resolves the hyperon puzzle without introducing any additional degrees of freedom.

Our understanding of the m.crobial involvem.nt in inflam.atory bowel disease (IBD) pathogenesis has increased exponentially over the past decade. The developm.nt of newer m.lecular tools for the global assessm.nt of the gut m.crobiom. and the identification of nucleotide-binding oligom.rization dom.in-containing protein 2 in 2001 and other susceptibility genes for Crohn’s disease in particular has led to better understanding of the aetiopathogenesis of IBD. The m.crobial studies have elaborated the norm.l com.osition of the gut m.crobiom. and its perturbations in the setting of IBD. This altered m.crobiom. or “dysbiosis” is a key player in the protracted course of inflam.ation in IBD. Num.rous genom.-wide association studies have identified further genes involved in gastrointestinal innate im.unity (including polym.rphism. in genes involved in autophagy: ATG16L1 and IGRm., which have helped elucidate the relationship of the local innate im.unity with the adjacent lum.nal bacteria. These developm.nts have also spurred the search for specific pathogens which m.y have a role in the m.tam.rphosis of the gut m.crobiom. from.a sym.iotic entity to a putative pathogenic one. Here we review advances in our understanding of m.crobial involvem.nt in IBD pathogenesis over the past 10 years and offer insight into how this will shape our therapeutic m.nagem.nt of the disease in the com.ng years.

An ever increasing dem.nd for zinc has resulted in worldwide efforts to exploit com.lex and lean grade reserves of zinc oxide ore. In this study experim.nts were done on zinc recovery from.high-fluorine bearing zinc oxide ore. First the effect of different variables on fluorine rem.val was investigated. Optim.m.experim.ntal conditions occurred when the tem.erature was 1173 K, roasting tim. was 90 m.n and air flow was at a velocity of 5 m.m.n, the fluorine rem.val from.the sam.les reached over 93%. The results obtained indicate that fluorine rem.val is not enhanced by adding diluted sulfuric acid or water as a binder. Second the roasted m.terials were leached with a diluted sulfuric acid, neutralized, flocculated and filtrated. The which satisfies the requirem.nt of fluorine residual fluorine content in the leached content in the leached solutions for the solutions was less than 38 m./L production of electrolytic zinc.

We report results from.a neutral hydrogen(H I)intensity m.pping survey conducted with a Phased Array Feed(PAF)on the Parkes *** survey was designed to cover 380 deg^(2)over the redshift range 0.3m. of 1.5 Gpc^(3))in four fields covered by the Wiggle Z Dark Energy *** results presented here target a narrow redshift range of 0.73m.lation pipeline was described,with an em.hasis on flagging of RFI and correction for signal loss in the data reduction process,particularly due to the foreground subtraction m.thodology.A cross-correlation signal was detected between the H I intensity m.ps and the Wiggle Z redshift data,with a m.an am.litude of=1.32±0.42 m.K(statistical errors only).A future Parkes cryogenic PAF is expected to detect the cross-correlation signal with higher accuracy than previously possible and allow m.asurem.nt of the cosm.c H I density at redshifts up to unity.
