Behavioral changes mediated by hunger in honeybees infected with Nosema ceranae

The microsporidian Nosema is a common honeybee pathogen which enters the adult bee orally and multiplies in its gut, imposing a metabolic demand on its host. The newly discovered Nosema ceranae, given its relatively new association with the European honeybee, is likely to be particularly severe in this regard. We therefore hypothesized that N. ceranae exerts a significant effect...

Can fatty acids and oxytetracycline protect artificially raised larvae from developing European foulbrood?

A quantitative assay for the transmission of European foulbrood (EFB) in artificially raised larvae was developed. This assay was used to determine the concentration of oxytetracycline (OTC) required to prevent larvae from developing EFB and whether 8 fatty acids (undecanoic, lauric [dodecanoic], myristic, myristoleic, ricinoleic, ricinelaidic, homo-y-linolenic and 13,16,19...

CIN2-Läsion? Da reicht womöglich aktive Überwachung aus

Die meisten CIN2(cervical intraepithelial neoplasia Grad 2)-Läsionen bilden sich spontan zurück, vor allem bei Frauen unter 30. Das schließen finnische Ärzte aus den Ergebnissen einer umfangreichen Metaanalyse.

B-ALL-Salvage: Vorteile für Immunkonjugat auch bei Älteren

Patienten über 55 Jahre mit rezidivierter akuter lymphatischer Leukämie (ALL) profitieren vom Immunkonjugat Inotuzumab ozogamicin (InO) genauso wie jüngere Patienten. Das ergab eine Subgruppenanalyse der Studie INO-VATE.

Honey bee stop-signal production: temporal distribution and effect of feeder crowding

The honey bee stop-signal may decrease recruitment by causing waggle dancers to cease dancing when food patch conditions deteriorate. However, little is known about how signaling may change during the time a signaler is inside the nest and what triggers signal production. All previous feeder studies have used crowded feeders to stimulate stop-signal production. We focused on...

Akupunktur gegen chronische Schmerzen: Metaanalyse bestätigt Therapieeffekte

Die Akupunktur in der Behandlung von chronischen Schmerzen ist immer noch umstritten — zu dubios erscheint manchen das zugrunde liegende Konzept. Eine aktuelle Metaanalyse dokumentiert nun aber erneut den Effekt der nadelgesteuerten Qi-Harmonisierung.
