PHOTOSYSTEM Ⅱ （PS Ⅱ） particles capable of O2 evolution contain reaction center polypeptides D1 and D2, cytchrome b559, chlorophyll （Chl）-binding proteins CP47 and CP43, three extrinsic polypeptides （with apparent molecular masses of 17, 23 and 33 ku） and cofactors needed for light energy conversion. After illumination, PS Ⅱ oxygen evolution complex （OEC） catalyzes the oxidization of water to molecular oxygen through S0→S4 redox state transition. The three extrinsic polypeptides have been revealed to be closely related to the photosynthetic O2 evolution.

Here the authors are interested in the zero set of Sobolev functions and functions of bounded variation with negative power of integrability. The main result is a general Hausdorff dimension estimate on the size of zero set. The research is motivated by the model on van der waal force driven thin film, which is a singular elliptic equation. After obtaining some basic regularity result, the authors get an estimate on the size of singular set; such set corresponds to the thin film rupture set in the thin film model.

The relative changes between shear and compressional velocities(RSP=(?)ln VS/(?) ln VP),bulk sound and shear velocities (RCS=(?) ln VC/(?) ln VS),and density versus shear wave velocity(RρS=(?) lnρ/(?) ln VS) in response to thermal and chemical variations were investigated for the pyrolitic lower *** heterogeneities with thermal origins,RSPincreases from 1.7 to 2.0 together with RρSdecreasing from 0.4 to 0.2 and RCS=～0.27 from the top to the bottom of the lower *** comparison,chemical variations (bulk iron or silica contents) are characterized by RSP0.5 at lower mantle *** values of RρSand RCSare indicative of chemical anomalies in the lower mantle,but a combination of thermal and chemical heterogeneities may be required to produce velocity and density anomalies at the magnitudes observed in seismic *** refinement of these characteristics requires data on the higher order pressure and temperature derivatives of the elastic moduli of the constituent phases.

This paper uses the boundary layer theory to obtain an asymptotic solution of the nonlinear educed wave equation. This solution is valid in the secular region where the geometrical optics result fails. However it agrees with the geometrical optics result when the field is away from the secular region. By using this solution the self-focusing length can also be obtained.

Aims: Male breast cancer represents - mor aggressiveness and drug resistance. CSCs are characterized by CD44 and/or ALDH1 expression. In this study, we investigated their expression in male breast cancer. Method: Two in situ ductal carcinoma (DCIS) and 18 invasive duc- tal carcinoma (IDC) male breast cancer cases were studied with Jefferson IRB approval. Membrane staining of CD44 was scored by the percentage of positivity. Cytoplasmic expression of ALDH1 was considered positive. Results: Ten cases had high CD44 expression, which were all IDC. Both DCIS and in situ component of IDC were CD44 low. ALDH1 was only positive in 15 IDCs. ALDH1+ cells were mostly in the invasive component. Both DCIS cases were negative for ALDH1. Among the 15 ALDH1+ IDCs, five with only invasive component had a higher percentage (aver- age 4.4%) of positive cells compared to the other eight with in situ components (average 2.0%). Metastatic cells in sen- tinel lymph nodes had a similar expression pattern of CD44 and ALDH1 as their primary tumor. Conclusion: CD44 and ALDH1 are expressed in male breast cancers and they are overexpressed in invasive cancer compared to carcinoma in situ. These findings suggest that CSCs play an important role in the progression to invasive carcinoma.

We report a case of pharyngeal foreign body with cutaneous migration in the form of a fishbone in a 24-year-old rural resident, presented with odynophagia, dysphagia, pain and left antero-latero-cervical swelling fistulated to the skin following ingestion of a fishbone during a meal that had been evolving for 2 weeks. Vital parameters were normal, with an unremarkable psychological examination. Clinical examination revealed a left antero-latero-cervical swelling that was painful to palpation, fistulous to the skin and draining frank pus, revealing a sharp fishbone. A standard X-ray showed that the foreign body had exited the pharynx and was located in the soft tissues of the lower neck. An exploratory cervicotomy was performed, allowing extraction of a serrated fishbone. The post-operative course was favorable.
