Sfenj

Sfenj (سفنج, safanj, "sponge") is the Moroccan yeasted doughnut: a wet, unsweetened flour-water-yeast-salt dough hand-shaped into a ring and deep-fried, eaten hot at breakfast, during Ramadan, and as the Hanukkah food of Moroccan Jews.

Sfermion

A sfermion is the hypothetical scalar superpartner of a Standard Model fermion in supersymmetry, named with a prefixed s (selectron, stop, stau); no sfermion has been observed, with squarks excluded below roughly 2 TeV.

SFN

SFN is a human protein-coding gene on chromosome 1 encoding stratifin, or 14-3-3 protein sigma, a checkpoint protein that prevents DNA errors during mitosis and is linked to several cancers.

SFP-DD

SFP-DD (Small Form-factor Pluggable Double Density) is a two-lane pluggable transceiver form factor for 100 Gbps networking, defined by an industry MSA group formed in 2017.

SFP28

SFP28 (Small Form-factor Pluggable 28) is a single-lane hot-pluggable transceiver form factor specified for 25 Gigabit Ethernet, electrically compatible with SFP+ and defined by the SNIA SFF-8402 specification.

SFpark

SFpark was a federally funded pilot of San Francisco's transit agency that adjusted parking rates by demand, and became a permanent citywide program in 2014.

SFPQ

SFPQ (PSF, splicing factor proline- and glutamine-rich), human DBHS-family nuclear RNA/DNA-binding protein with NONO and PSPC1; essential for NEAT1 paraspeckles, splicing, transcription, DNA repair, influenza transcription, and ALS-linked nuclear loss.

SFR (Forsmark)

SFR (Swedish: Slutförvar för kortlivat radioaktivt avfall) is an underground repository at Forsmark, Sweden, where SKB has deposited short-lived radioactive waste in bedrock beneath the Baltic Sea since 1988.

SFR1/Mei5 family

SFR1/Mei5 family (InterPro IPR018468): conserved eukaryotic proteins (Sfr1, Mei5) that pair with Swi5/Sae3 to form recombination mediator complexes stimulating Rad51 and Dmc1 DNA strand exchange, from yeast to humans.

SFRP1

SFRP1 (secreted frizzled related protein 1, FRP, FrzA, SARP2) is a human gene at 8p11.21 encoding a secreted 36-kDa Wnt signaling modulator; its epigenetic silencing is linked to cancer, and loss alters bone formation.

SFRP2

SFRP2 (secreted frizzled related protein 2, SDF5/SARP1), a secreted CRD/NTR-domain glycoprotein on human chromosome 4q31.3, modulates WNT signaling context-dependently and acts in development, fibrosis, angiogenesis, and cancer.

SFRP4

SFRP4 (sFRP-4, PYL), gene ID 6424 at 7p14.1, encodes a 346-amino-acid secreted Wnt decoy receptor, the largest SFRP family member; loss causes Pyle disease and altered expression marks cancers and diabetes.

SFSS trial

SFSS trial (Spinal Fusions Steroid Study, NCT05287035), University of Texas at Austin Early Phase 1 randomized triple-blind trial of perioperative IV dexamethasone versus saline in 70 children aged 10 to 18 undergoing posterior spinal fusion for adolescent idiopathic scoliosis.

SFTPA1

SFTPA1 (surfactant protein A1, SP-A1) is a human chromosome 10q22.3 gene encoding a collectin lung surfactant protein involved in surfactant homeostasis, innate immunity, and interstitial lung disease and lung cancer risk.

SFTPC

SFTPC (SP-C, surfactant protein C gene, OMIM 178620) is a human gene on chromosome 8p21.3 encoding the hydrophobic lung surfactant protein SP-C; mutations cause pulmonary surfactant metabolism dysfunction type 2 and interstitial lung disease.
