We present radial velocity follow-up obtained with ESPRESSO of the M-type star LTT 1445A (TOI-455), for which a transiting planet b an orbital period 5.4 days was detected by TESS. report discovery second (LTT c) and third non-transiting candidate d) periods 3.12 24.30 days, respectively. The host is main component triple M-dwarf system at distance 6.9 pc. used 84 high-resolution spectra to det...

ABSTRACT There is a lack of exoplanets with sizes similar to Neptune orbiting their host stars periods ≲3 d – hence the name ‘sub-Jovian/Neptune desert’. Recently, several have been confirmed reside in desert, transforming it into ‘savanna’ ‘giraffe’ planets (such as LTT 9779 b and TOI-674 b). The most prominent scenarios put forward for explanation formation desert are related stellar irradiat...

Clinically used somatostatin (SRIF) analogs, octreotide and lanreotide, act primarily by binding to SRIF receptor subtype 2 (sst2). In contrast, the recently described multiligand SOM230 binds with high affinity to sst(1-3) and sst5 and KE 108 is characterised as a high affinity ligand for all five SRIF receptors. In tumoural mouse corticotrophs (AtT-20 cells) and in mouse hippocampus, binding ...

The hypothesis, that hypoiodemia of goats causes such a compromise of the immune system, which during subsequent Toxoplasma gondii infections results in clinically more pronounced signs of toxoplasmosis, was verifying in laboratory mouse. Hypoiodemic mice (fed by wheat and supplied by water), normoiodemic mice (fed by wheat and supplied by water containing 1.25 mg KI/l) and the majority of stan...

The lymphocyte transformation test (LTT) was used to elucidate whether certain side effects induced by radiographic contrast media have an immunologic etiology. Groups studied were: 8 patients who had previously experienced adverse reactions in association with urography, 6 patients who underwent urography without notable side reactions, 17 occupationally exposed nurses, and 9 unexposed control...

ABSTRACT In spring 2002, an unusual disease outburst was recorded on Norway spruce seedlings in southeast Norway. Extensive damage was recorded on 1- and 2-year-old Norway spruce seedlings that either had wintered in nursery cold storage or had been planted out in autumn 2001. The damage was characterized by leader shoot dieback and stem necroses on the upper or lower part of the shoot from 200...

We present La and Cu NMR relaxation measurements in single crystal La1.67Eu0.2Sr0.13CuO4. A strong peak in the La spin-lattice relaxation rate observed in the spin ordered state is well described by the BPP mechanism @Bloembergen, Purcell, and Pound, Phys. Rev. 73, 679 ~1948!# and arises from continuous slowing of electronic spin fluctuations with decreasing temperature; these spin fluctuations...

Hypersensitivity reactions to titanium (Ti) are very rare. Thus, we assessed the proinflammatory response and also potential tolerance favoring in vitro reactivity of human blood lymphocytes and monocytes (PBMC) to Ti in healthy individuals (14 without, 6 with complication-free dental Ti implants). The proliferation index (SI) in lymphocyte transformation test (LTT) and production of cytokines ...
