The P515/535 module has become available as a new accessory for the DUAL-PAM-100. It serves for simultaneous measurements of the dual beam 550 515 nm difference signal, reflecting the electrochromic pigment shift (ECS, P515), and of the single beam 535 nm signal, reflecting "membrane energization" ("scattering" changes). The technical features of the emitter and detector units of the new device...

Optical switching offers the potential to significantly scale capacity of data center networks (DCN) with a simultaneous reduction in time and power consumption. Previous research has shown that end-to-end time, which is sum switch configuration clock recovery (CDR) locking should be kept within few nanoseconds for high network throughput. This challenge low motivated into fast optical switches...

Various organophosphorus compounds, particularly those with low acute toxicity levels, such as Fenitrothion (common name; Sumithion), Fenthion (common name; Baycid) and Pyridaphenthion (common name; Ofunack), are widely used as insecticides around the world. PAM (2-Pyridinum aldoxime methiodide), the specific antidote against Parathion, is not very effective against poisoning by these organopho...

Placenta-sequestering Plasmodium falciparum involved in the pathogenesis of pregnancy-associated malaria (PAM) in otherwise clinically immune women expresses particular variant surface antigens (VSA(PAM)) on the surface of infected erythrocytes that differ from VSA found in parasitized nonpregnant individuals (non-PAM type VSA). We studied levels of immunoglobulin G (IgG) and IgG subclasses wit...

Peptidylglycine alpha-amidating monooxygenase (PAM) is an essential enzyme that catalyzes the COOH-terminal amidation of many neuroendocrine peptides. The bifunctional PAM protein contains an NH2-terminal monooxygenase (PHM) domain followed by a lyase (PAL) domain and a transmembrane domain. The cytosolic tail of PAM interacts with proteins that can affect cytoskeletal organization. A reverse t...

Group A streptococci (GAS) display receptors for the human zymogen plasminogen on the cell surface, one of which is the plasminogen-binding group A streptococcal M protein (PAM). Characterization of PAM genes from 12 GAS isolates showed significant variation within the plasminogen-binding repeat motifs (a1/a2) of this protein. To determine the impact of sequence variation on protein function, r...

Cardiac Hydatid cyst is uncommon, but life threatening. Cardiac involvement occurs in only 0.5-2% of all hydatid infestations. In this report, we present a case of hydatid cyst located in the right atrium adjacent to tricuspid annulus, which was excised surgically (Pam Med J 2008;2(2):98-100).

Photoacoustic microscopy (PAM) is a hybrid in vivo imaging technique that acoustically detects optical contrast via the photoacoustic effect. Unlike pure optical microscopic techniques, PAM takes advantage of the weak acoustic scattering in tissue and thus breaks through the optical diffusion limit (~1 mm in soft tissue). With its excellent scalability, PAM can provide high-resolution images at...

Peptidylglycine alpha-amidating monooxygenase (PAM), an integral membrane protein essential for the biosynthesis of amidated peptides, was used to assess the role of cytosolic acidic clusters in trafficking to regulated secretory granules. Casein kinase II phosphorylates Ser(949) and Thr(946) of PAM, generating a short, cytosolic acidic cluster. P-CIP2, a protein kinase identified by its abilit...
