background: indisputable population exposure to widespread electromagnetic fields, has grown concerns over the probable health effects of these fields. objective: the present study was aimed to examine the possible effects of 50 hz extremely low frequency electromagnetic field (elf-emf) exposure on the number and quality of mice blastocysts. materials and methods: in present study, 66 nmri preg...

Two oxytrichid ciliates collected from China, Oxytricha lithofera Foissner, 2016 and Rubrioxytricha haematoplasma (Blatterer 1990) Berger, 1999 were investigated based on living observations, protargol preparations, molecular analyses. The Chinese population of O. shares highly distinctive features with the type population, e.g., lithosomes, abutting macronuclear nodules, straight undulating me...

Southern Taiwan’s Kenting National Park is a popular retreating place for many domestic and international tourists, with increasing tourist numbers potentially over-burdening the coastal ecosystems. To better understand human impacts, long-term ecological research program was initiated in 2001 to track water quality at 14 coral reef-abutting sites throughout park since then. Extracting data fro...

Chan DWC, et al. BMJ Case Rep 2017. doi:10.1136/bcr-2017-220057 Description A woman aged 67 years was referred with pituitary enlargement identified on CT scan. Imaging was performed to investigate a progressive, incapacitating, 12-month history of nausea, vertigo, gait disturbance and recurrent falls. Her presentation included chronic occipitofrontal headaches, which had increased in severity ...

Seasonal subsurface temperature monitoring, which exploits the fact that increased seepage flow may locally alter distribution, is a useful approach for leakage monitoring and evaluation within embankment dams their foundations. At Mactaquac Generating Station, New Brunswick, Canada, spatial temporal variations of have been monitored modelled at steeply inclined interface between compacted clay...

Purpose  Radiotherapy treatment planning of extended volume typically necessitates the utilization of multiple field isocenters and abutting dosimetrically matched fields in order to enable coverage beyond the field size limits. A common example includes total lymphoid irradiation (TLI) treatments, which are conventionally planned using dosimetric matching of the mantle, para-aortic/spleen, and...

Cell migration entails the formation of cellular protrusions such as lamellipodia or filopodia, the growth of which is powered by the polymerisation of actin filaments abutting the plasma membrane. Specific Rho-GTPase subfamilies are able to drive different types of protrusions. However, significant crosstalk between Rho-family members and the interplay of distinct Rho-effectors regulating or m...

Lobate features abutting massifs and escarpments in the middle latitudes of Mars have been recognized in images for decades, but their true nature has been controversial, with hypotheses of origin such as ice-lubricated debris flows or glaciers covered by a layer of surface debris. These models imply an ice content ranging from minor and interstitial to massive and relatively pure. Soundings of...

The chemical synthesis of polypeptide chains >50 amino acids with prescribed sequences is challenging. In one approach, native chemical ligation (NCL), short, unprotected peptides are connected through peptide bonds to render proteins in water. Here we combine chemical ligation with peptide self-assembly to deliver extremely long polypeptide chains with stipulated, repeated sequences. We use a ...
