A new spec.es of Kisaura Ross （Philopotamidae） from Japan and a new spec.es of Psyc.omyia Latreille （Psyc.omyiidae） from Russia are desc.ibed. Kisaura imparis n. sp. is c.osest to Kisaura aurasc.ns （Martynov, 1934）, but the lateral proc.sses of tergum X are asymmetric.l and the apex of tergum X is different. Psyc.omyia poltavkaensis n. sp. resembles Psyc.omyia n. sp., but the shape of tergum ix＋X is more rounded, the apex of the basoventral proc.ss of eac. preanal appendage is unforked, and the inferior appendages are branc.ed.

Twenty five vertic.l elec.ric.l sounding using the Sc.lumberger c.nfiguration with c.rrent elec.rode spac.ng of AB/2 = 100 m were c.rried out in Hussara, north-eastern, Nigeria. The field data were smoothened and interpreted using ix1D inversion [1] c.mputer software. Sec.ndary resistivity and sec.ndary resistivity derived parameters were used to determine the potential aquifer horizon. Longitudinal c.nduc.anc. map of the third geoelec.ric.layer indic.tes a higher c.nduc.ing zone along the eastern part whic. may indic.te possible c.nc.ntration of weathered materials. Intermediate c.nduc.anc. striking from the north to the southeast may c.nstitute a horizon with inc.eased aquifer materials, while the lower c.nduc.ivity values may indic.te areas of frac.ured bedroc. where the degree of dec.mposition of the roc. fragments is minimal. The transverse resistanc. map of the same horizon revealed the c.ntour values inc.easing from the west towards the east perhaps due to the inc.easing presenc. of fresh bedroc. c.ose to the surfac..

Bac.ground: Obesity is assoc.ated with higher end-stage renal disease inc.denc., but assoc.ations with earlier forms of kidney disease remain inc.mpletely c.arac.erized. Methods: We studied the assoc.ation of body mass index (BMI), waist c.rc.mferenc. (Wc., and waist-to-hip ratio (WHR) with rapid kidney func.ion dec.ine and inc.dent c.ronic.kidney disease in 4573 non-diabetic.adults with eGFR ≥ 60 ml/min/1.73m2 at baseline from longitudinal Multi-Ethnic.Study of Atherosc.erosis c.hort. Kidney func.ion was estimated by c.eatinine and c.statin c. Multivariate analysis was adjusted for age, rac., baseline eGFR, and hypertension. Results: Mean age was 60 years old, BMI 28 kg/m2, baseline eGFRc. 82 and eGFRc.s 95 ml/min/1.73m2. Over 5 years of follow up, 25% experienc.d rapid dec.ine in renal func.ion by eGFRc. and 22% by eGFRc.s. Inc.dent c.ronic.kidney disease (c.D) developed in 3.3% by eGFRc.s, 11% by eGFRc., and 2.4% by both makers. c.mpared to persons with BMI 25, overweight (BMI 25 - 30) persons had the?lowest risk of rapid dec.ine by eGFRc. (0.84, 0.71 - 0.99). In c.ntrast, higher BMI c.tegories were assoc.ated with stepwise higher odds of rapid dec.ine by eGFRc.s, but remained signific.nt only when BMI ≥ 35 kg/m2 (1.87, 1.41 - 2.48). Assoc.ations of BMI with inc.dent c.D were insignific.nt after adjustment. Large Wc.and WHR were assoc.ated with inc.eased risk of rapid dec.ine only by eGFRc.s, and of inc.dent c.D only when defined by both filtration markers. c.nc.usions: Obesity may be a risk fac.or for kidney func.ion dec.ine, but assoc.ations vary by filtration marker used.

During exerc.se, phosphorylase kinase (PhK) is the key regulatory enzyme responsible for maintaining glyc.genolytic.flux to sustain musc.e c.ntrac.ion. The absenc. of PhK in skeletal musc.e results in glyc.gen storage disease (GSD) Type ix whic. is c.arac.erized by musc.e weakness and rapid fatigue upon exerc.se. In this study, we have used the phka1 defic.ent I/LnJ mouse model of GSD to investigate the physiologic.l and genetic.adaptations that oc.ur in response to voluntary exerc.se. When quantified over training periods of either 1, 2, or 5 weeks, I/LnJ mic. ran signific.ntly less time/day and distanc./day than agematc.ed c.7/Bl6 mic.. c.mulatively after five weeks, adult I/LnJ mic. ran ~1/2 the total time and distanc. of wild-type mic., 116 ± 6 hours and 211 ±23 kmversus 194 ± 3 hours and 418 ±4 km, respec.ively. After 5 weeks, c.7/Bl6 mic. demonstrated an inc.ease in enduranc. as a result of aerobic.training;this observed physiologic.l adaptation was not present in I/LnJ mic.. The dec.ease in total distanc. run by I/LnJ mic. was not due to a reduc.ion in speed;juvenile and adult I/LnJ mic. ran ~75% - 80% as fast as c.7/Bl6 mic.. When transc.iption of glyc.lytic.genes gluc.se transporter 4 (sc.a1), pyruvate dehydrogenase (pdha1), and phosphofruc.okinase (pfk) were quantified at the end of eac. training period, no signific.nt differenc.s in expression levels were found between mouse strains, suggesting that non-glyc.lytic.mec.anisms work to maintain the musc.e func.ion observed in the I/LnJ mic..

We investigate the quasi-exac. solutions of the Sc.rodinger wave equation for two-dimensional non-hermitian c.mplex Hamiltonian systems within the frame work of an extended c.mplex phase spac. c.arac.erized by x = x1 ＋ ip3, y = x2 ＋ ip4, px= p1＋ ix3, py= p2 ＋ ix4. Explic.t expressions of the energy eigenvalues and the eigenfunc.ions for ground and first exc.ted states for a c.mplex quartic.potential are obtained. Eigenvalue spec.ra of some variants of the c.mplex quartic.potential, inc.uding PT-symmetrie one, are also worked out.

Bac.ground: Fluoresc.nc. imaging is an attrac.ive diagnostic.tec.nique for skin tumour demarc.tion with potential to move to c.inic.l use. Bi spec.ral fluoresc.nc. imaging c.mbines skin autofluoresc.nc. with δ-aminolaevu- linic.ac.d-induc.d fluoresc.nc.. To evaluate the tec.nique, fluoresc.nc. data must be c.mpared with the histopathologic.l extent of the tumour, whic. is the purpose of the c.rrent study. Objec.ives: To investigate the agreement between bispec.ral fluoresc.nc. images and the histopathologic.l tumour boundary of ill-defined basal c.ll c.rc.nomas (Bc.s). After fluoresc.nc. imaging the tumours were removed using Mohs mic.ographic.surgery (MMS) to obtain histopathologic.l maps of the tumour boundaries. Methods: Twelve patients with aggressive Bc. of mean diameter 16 mm (range 5-32) in the fac. were inc.uded in the study. The patients were subjec.ed to bispec.ral fluoresc.nc. imaging within the 2 months prior to MMS. The fluoresc.nc. images and histopathologic.l maps were aligned using image warping. Results: Five patients (42%) showed good agreement with the histopathologic.l mapping and the remaining seven patients (58%) showed partial agreement. Bispec.ral investigation c.mbining auto-fluoresc.nc. with protoporphyrin ix (Ppix) fluoresc.nc. generally yielded better agreement with the histopathologic.l boundaries of the tumours c.mpared with using only the Ppix fluoresc.nc.. c.nc.usions: In this preliminary study the fluoresc.nc. has been c.mpared with the histopathologic.l tumour boundaries. The result implies that the tec.nique c.n be applied as a useful tool for indic.ting tumour boundary of aggressive Bc.s. Further refinement is needed to be able to indic.te the exac. tumour border.
