Abstract
SARS-CoV-2 infection has been associated with multiple neurological manifestations. One such manifestation, which has been described since the early stages of the COVID-19 pandemic and is relevant for current neurological practice, is Guillain-Barré syndrome (GBS). The literature describes neurotoxic mechanisms of the virus itself and the possible pathways by which it may affect the peripheral nerves in experimental studies; however, we still lack information on the mechanisms causing the immune response that gives rise to GBS in the context of SARS-CoV-2 infection. Colombia is one of the Latin American countries worst affected by the pandemic, with the third-highest number of cases in the region; thus, it is essential to recognise GBS, as this potential postinfectious complication may severely compromise the patient's functional status in the absence of timely diagnosis and treatment. We present a series of 12 cases of GBS associated with SARS-CoV-2 infection from hospitals in 4 different Colombian cities and describe the clinical presentation, laboratory and electrophysiological study findings, and treatment.

Abstract
AIM OF THE STUDY A total of 27 ethanolic plant extracts from 27 species were screened for leishmanicidal activity in vitro against Leishmania amazonensis. Most of the selected species (19) are traditionally used by the Chayahuitas, an Amazonian Peruvian ethnic group, to treat skin affections and/or leishmaniasis. MATERIAL AND METHODS A colorimetric method based on the reduction of tetrazolium salt (MTT) was used to measure the viability of Leishmania amazonensis promastigote and amastigote stages. RESULTS AND CONCLUSIONS Only the leaves of two species of the Piperaceae family (Piper hispidum Sw., and Piper strigosum Trel.) showed good leishmanicidal activities (IC(50)<10 microg/ml against amastigotes). Roots of Tabernaemontana sananho Ruiz & Pav. (Apocynaceae), together with bark of Vismia tomentosa Ruiz & Pav. (Clusiaceae), fruits of Solanum straminifolium var straminifolium Jacq. (Solanaceae), and stems of Zamia lindenii Regel ex André (Cycadaceae) showed low activity against amastigote stage (IC(50) around 50 microg/ml). Of those only Tabernaemontana sananho displayed also good activity on promastigotes (IC(50)<10 microg/ml). Results are discussed herein, in relation with the traditional use of the plants and compared with other data from the relevant literature.

Abstract
The experiments reported examine the effects of two highly related variables, word frequency and age of acquisition, on short-term memory span. Short-term memory span and speech rate were measured for sets of words which independently manipulated frequency and age of acquisition. It was found that frequency had a considerable effect on short-term memory span, which was not mediated by speech rate differences--although frequency did affect speech rate in one experiment. For age of acquisition, this situation was reversed; there was a small but significant effect of age of acquisition on speech rate, but no effect on memory span. This occurred despite results confirming that the stimuli used in the experiments produce an effect of age of acquisition on word naming. The results are discussed in terms of a two-component view of performance on short-term memory tasks.

Abstract
A growing literature--most uncontrolled--suggests that lithium may be useful in the treatment of some non-manic-depressive personality disorders. The diabolical behavior, conversion symptoms, and diffuse violence and cruelty of a young woman responded remarkably to treatment with lithium. Blind substitution of a placebo confirmed a lithium effect. Patients with the DSM-II diagnosis of explosive, antisocial, and hysterical personalities would appear to be the best candidates for a trial of lithium.
