Assessing shipping noise as a potential driver of harbour seal (Phoca vitulina) habitat selection

NAMMCO Scientific Publications
Over the past decade, anthropogenic noise from activities such as shipping has significantly increased in the ocean, raising questions on their potential impact on coastal species such as harbour seals.

Plaid‐Like Spin Splitting and Chirality of Magnon Bands in Antiferromagnetic MnTe2

Advanced Science, EarlyView.
Helicity‐ and angle‐resolved Raman spectroscopy reveals chiral magnons in the non‐coplanar antiferromagnet MnTe 2. Combined with first‐principles calculations and spin‐wave theory, the results establish its altermagnetic character through circular Raman dichroism, reduced rotational symmetry, and a distinctive plaid‐like momentum‐space magnon spin ...

Comparative nasal and anal microbiomes in sympatric ringed and harbour seals: insights into host adaptation and niche differentiationComparative nasal and anal microbiomes in sympatric ringed and harbour seals: insights into host adaptation and niche differentiation [PDF]

Royal Society Open Science
Understanding the microbiomes of marine mammals is essential to explore their health, ecological roles and responses to environmental change. We investigated the nasal and anal microbiota of two sympatric subarctic seals, the harbour seal (Phoca vitulina)

The world's northernmost harbour seal population-how many are there? [PDF]

PLoS ONE, 2013
This study presents the first abundance estimate for the world's northernmost harbour seal (Phoca vitulina) population, which resides in Svalbard, Norway, based on three digital stereoscopic photographic surveys conducted in 2009 and 2010.

Trafficking Deficiency of TMEM175 Variants in Parkinson's Disease Pathogenesis and the Prospects of Precision Medicine

Advanced Science, EarlyView.
This study identifies that the PD‐associated TMEM175‐L156P variant disrupts lysosomal ion channel trafficking by causing aberrant endoplasmic reticulum retention. A “chaperone–agonist” bifunctional small molecule restores TMEM175‐L156P lysosomal localization and channel function, thereby alleviating PD‐relevant cellular phenotypes and highlighting a ...

The pathology and occurrence of pathogens in Scottish grey seals (Halichoerus grypus). [PDF]

, 2014
Neonatal mortality in grey seals on the Isle of May breeding colony and in a rehabilitation centre were investigated by detailed systematic post-mortem examinations (n=59), on-site bacteriology and advanced molecular diagnostic techniques for specific ...

Establishing the relative importance of sympatric definitive hosts in the transmission of the sealworm, Pseudoterranova decipiens: a host-community approach

NAMMCO Scientific Publications, 2001
The importance of a given host to a particular parasite can be determined according to three different criteria: host preference, host physiological suitability and host contribution to transmission. Most studies on the sealworm Pseudoterranova decipiens

The Natural Product Corramycin Acts as a DNA Gyrase Poison and Overcomes Fluoroquinolone Resistance in Mycobacterium tuberculosis

Advanced Science, EarlyView.
Corramycin, a myxobacterial natural product antibiotic, exhibits potent bactericidal activity against multidrug‐resistant Mycobacterium tuberculosis. The compound hijacks bacterial transporters such as BacA and OppABCD to enter the cell and inhibits DNA synthesis through a previously unrecognized mode of DNA gyrase poisoning, locking the enzyme in an ...

Interactions between seals and salmon fisheries in Tana River and Tanafjord, Finnmark, North Norway, and possible consequences for the harbour seal Phoca vitulina

Fauna Norvegica, 1997
In the 1820’s, a relatively large harbour seal population may have inhabited the Tana River Estuary. Due to heavy persecution, especially in the 1920’s and 1930’s, it was reduced dramatically, and today there are probably less than 40 individuals left ...

Gαi1/3 Are Essential for BMP2‐Induced Osteogenesis by Bridging BMP Receptors to the Gab1 Signaling Complex

Advanced Science, EarlyView.
The Gαi1/3 protein is a crucial connecting protein closely related to the signal transduction process of bone formation‐related cytokines such as BMP2. Gαi1/3 mediates downstream signaling pathways such as Smads and MAPK by binding to adaptor proteins like Gab1, thereby promoting the osteogenic effect of BMSCs.
